Overall nice job. While I find it odd that an archer will be wearing what appears to be nothing but a metal top and bikini bottom with a cape attached, I know that such seems to be the popular notion these days. Also I notice that the knees are distorted on the archer some, and the feet n Maia seem to be missing. Perhaps a cut-off? Someone has mentioned it is to reflect the way she is facing the screen, but looking at the ways her legs are positioned, I think you would see some sort of a foot there.
Also, I think that the blue girl doesn't quite fit in with the rest. While the style is similar, the shading or detail seems to be somewhat different.
But hey, it is a heck of a lot better than I could do!
