First, before any misunderstand:
I always upload my work at either my dropbox or my sta.sh before uploading anywhere else. This is because I'm really critic with my drawings so I only upload what I think it's good to be uploaded. You can see this with February,April and May.
Regards, there are times when in a month I think "Hey, that's good" so I upload at other sites, such as theotaku, deviantart and toy.house. For doing this I used my sta.sh and my dropbox as a guide.
Now, let's talk about 2015...
Big change: Moved to my Uni (that's actually REALLY far away from my parents home) and starting working on major in Digital Design with focus on character design and concept art.
For me, someone that never had any art classes, they were the most precious things: the anatomy classes, the works, the homeworks...everything made me to call this year the year of improvement.
Now...let's summarize the months o/

January:January is always a busy month for me, but this year was busier then any other. With university right by the corner, I spend more time finding somewhere to stay at the new city and buying crucial stuff(like pan, house stuff, clothes,etc) then drawing. I made a few chibis here and there, this SeeU one being my favorite. SeeU is my favorite vocaloid and I did this while listening "'Leaving in Summer, yet you're in my Fluffoughts'.

February: I didn't draw much in February...I was too excited and scared with university, so I only did some sketches and unfinished pieces.That's actually a failed contest entry that I gave up. I focused more on the fabrics and textures then the anatomy here.

March:Oh La March...the month of the realism xD Or semi-realism. With classes all pumped up, I wanted to do something good for the month display at my University, so I drew many things. In the end, the University displayed the pink girl on a big cavas and I was so proud and happy for that >.< That's also my mother favorite, so I had do put in here xD

April:The month of the human anatomy...sketches, lots and lots of sketches. Over 200 sketches of human anatomy all over my sketchbook.Bus ride? Sketch! Lunch time?Sketch! In the movies with friends? Sketch! I used all the opportunity to sketch something and I always ended up asking for some random guy to be my model. I made lots of nice friends that way, and I also became more critic with my anatomy, to the point to throw my paper away if there was one little mistake. Also started to see how beautiful the human body is...specially the man body, with all the muscles and bones, like a poetry.

May: Disney fetish? Yes! I won a contest in my University and one of the prizes was a beautiful Walt Disney ArtBook. That book is my main influence, and I all did that month was disney related things. The new Cinderella movie was also coming so I made many Cinderella fanart.

June:University was crazy, so many things to do (and tougher for me, since I didn't liked to receive anything less then 9, so I worked like crazy this mat month). Started playing with colors more and more, trying new shading and blending techniques. I also started giving private lessons on digital painting, specially on hair. There were days that I had 6 classes to give plus my University works and papers. I made some nice profit that month and was able to buy "Anatomy for the Artist" book. It's my little treasure <3

July:(I don't know if that's from July...but I found it on my July folder at the dropbox...and I really like this so...) Social life? Free time? What are those abstract words? I was practically a walking zombie by that point. If I did more then 8
"big" drawings that month, it was too much. I only scribled things on my sketchbook
and I also had a really nice(REALLY nice) friend that agreed to be my nude model for two weeks. I mean...human anatomy...there is never enough room to learn more about it, right? (that was the month of the NSFW pics.)

August: SCHOOL BREAK YAY!Winter vacation and I was able to breath! Did so many drawings that month, and I was experimenting with my style. Made some crucial studies for concept art and color scheme.

September: Yay...Uni is back! And I was invited to be a part of an art group that displayed their artwork with a nice sponsor behind it! The sponsor was a comic book and usual nerd/geek stuff shop and they wanted us to make something for the upcoming Suicide Squad movie.Each person needed to draw a character and I ended up making Harley Quinn. I loved it so much!! (we displayed her art this month at the Brazilian Comic Con! I was so nervous in signing and not believing when people were actually buying the poster!)

October: My grades were established with my beloveds 9 and 10 so I had free time! Started doing RP's again and my favorite couple, Myko and Cameron, were all I could draw.

November:Needed to upgrade my deviantID! So I made a nice portrait of myself...that my friends ended up loving so much that they suggested for the University to display...and they displayed it >.< I also started to making contacts for the future, and also started making plans for a abroad school application.Started working on my ArtBook project and Nicholas became the voice of my Graduation Course, since it's a new course.

December:The month is still running and I'm not done yet! I'm reading more and more books about colors and I bought a new anatomy book and I also won the ArtBook award, which is going to give me a Wacom Intuos 5 Pro Large as a prize and also a small scholarship. The drawing featured here is a tribute to the old pottermore, my character Lo whose house was Slytherin and the site that made my days brighter and where I had met many incredible people is now gone. But the feeling remain! I'm not done with this, but I'm liking the overall result and it's really my best December art.

I hope 2016 be as good as 2015, and that I can thrill my path to becoming a concept artist and not freak out about my grades (I can't even sleep when I think something is not 10 worth it), and I hope to be closer to my brother and boyfriend even though we are going to be apart again.
These two are my inspiration and strength, my family is also but they are the ones that make me improve so much with their critiques and help, I would be nothing without them :')
