That's looking *very* good. Not familiar with the characters myself, but that won't stop me from really liking the techniques you used for the shading and lighting, with the purple for the shaded and yellow for the lighted parts. Nice poses as well and i love the way the colors of the pupils fade from the pink-ish into the yellow.
Only thing i'm not as fond of is the background.
After writing that last paragraph, read the backgrounds now and recall reading about Honey's crossover in Fighting Vipers to Sonic, after getting interested in it through Matt McMuscles video on FV2 and doing some research.
In any case, just a real good piece.
