I know Riko's hot and all... but shift your eyes to the right a bit. See "Lolo". His anatomy is very unbalanced. (And not in an acceptable animu way). One observation would be the size of his hands in relation to the size of his head (or face).
OP. Do you "flip-rotate" your stuff? When drawing it's easy to get lost in the little details and miss the big picture. Mirroring an image can open your eyes to issues you had overlooked.
