This is nice, I like the colors you used in particular. I think his far leg is too dark, there shouldn't be that much of a difference, if much at all, in my opinion. Especially if you don't make a change in difference with his foot. Right now it pops out since the leg is dark but the foot is not. In most places you have a black outline but in some places you get rid of it. This would be fine, but I don't see a consistency in how you do it. The bottle could use highlights to show that it is a solid, round object.
Good work, I'm looking forward to seeing more from you.
