I did this Celty sketch/final piece around January, just to have fun and relax a bit. I did this with a sketch pencil only, I didn't use a reference since I had finished rewatching one of the last episodes I was able to remember the important details. :) Photographic Memory can help in terms like that thank you you Mena for such a gift :)
Also if you maybe you'd like to just check on your side time my work, I post almost everything on Deviantart, a lot of my work is scanned to have a better quality than a camera of a phone.
