Added opposing foot. Thanks for the tips MayU, I took your advice - I think it looks better. Member reactions:
you need to show the sumos' off-leg on the other side of the horse. As it is it merely looks like he is constipated on this side.
I love this, but I agree about the foot. Maybe if you could raise it off the ground a little more...kinda skew him or shorten him, it would look more like his foot is off the ground versus on the ground with poor shadow.
