RENDERING SKETCH BOOK

In these days I'm working on 3d animation in a scene with a lot of characters, so when I launch my rendering I have to wait a lot of time, therefore I have a little time with nothing to do, so I decided to draw someting. For my birthday my bestfriend give me a sketch book, so I'm painting on it. They aren't nothing of special but I want share it with you, guys! :D
