Here is another update, redrew it using the same the same pallet but taking some colors out of it. The redraw is a larger piece and the anatomy and pose makes a bit more sense. Falling asleep crosslegged with weird foot angles isn't that convincing..
Thoughts on this version?
[EDIT]: On retrospect I think the right hand (his left) could do with tidying, and the shading on the soles of the feet. Animation in this would probably be nice too.
[EDIT EDIT]: Annd I will saturate his feet some more in the next update. Any advice/recommendations?
