well i dunno, its head looks a lttle too big for its head and its eyes look like they're going in two diff. directions. the tail looks a bit... boxy when it should be curvy. Hope that helps.
Comments:
the coloring is great =D and i also love the background.
not too bad, but i think it's kinda cute; might need a bit more work, but other than that, i'd say it looks like mew when it is an adolescent (teenager).
