As much as i like the composition and look of the piece, i cant help but be saddened by your texture use. This would look totally great if you had just painted in the color or at least match up the textures with the outlines.
this is just really pretty! and i love how you colored them! especially princess peach's dress it looks so pretty! wait i just noticed what you did that looks so awesome! especially princess peach's hair i like how you did that! it looks so natural
