I really like this model. The form is overall very nicely drawn and the design is very detailed and creative. My goodness, those colors as well as how well the contrast is shown between the character and the background. If anything, I think the proportions on the face are a little unclear. It's like it tried to be a 3/4 but due to its lack of structure, it kind of looks a bit like a melted frontview. I think the other side of the face should line up a little better as well as the eye being put in more of a smooth "curve", like if there was a wave between the eyes to signal the perspective.
This is otherwise just a very nicely composed drawing, and for pixel art, the detail is very meticulous.
