I made a drawing of "cloudy wolf"'s logo in order to make it my portfolio's cover in a previous submission.

However, I thought, "why attach a paper sheet if the portfolio is black and has a nice surface? It'd look better if I drew the logo directly in it, right?"

I liked best that new idea, so I traced the drawing -which you can see there in the pic- , colored with a silver-colored Prismacolor and outlined a bit with a black pen. -the only problem is that I haven't figured out a good way to protect it yet, but it doesn't seem to get damage easily anyway.

I liked it so much I got a bit excited on personalizing other stuff in a similar way. Now I got the hang of this, I've been thinking about making a fully-colored dragon in another black portfolio I have over here, but I'd like to experiment a bit first to see if it'd be a good idea to add so much color and how it'd behave over time so I don't waste my portfolio xD
