Here is a little piece I did to help a friend of mine. He and his wife are writing a nice story and I'm creating some visual for them.
I think the lighting is pretty successful but I need to work hard on my anatomy skills... I should say application of my anatomy knowledge.
I know quite well anatomy. construction of it and physiology but I'm having a hard time putting it down on paper. I always something is off. I'm still doing a lot of practicing; fold study, poses, colors, light and shadows, composition, storyboard....etc.
