Nice coloring, maybe it would be greater if your lights were more logical:

- on the right character face shadows are quite ambiguous, I wonder if light comes from left or right. However, this is not very important for the image quality

- some more shadows on legs may accentuate perspective and make the character more impacting - just try to distinguish first and second plan using colors

- purple shadows (on left) may be darker on the top part where the costume is darker. This problem can be solved using grey tons as a first layer, making shadows homogeneous and independent of the chosen color.

Thats all , heep that nice work on !
