apparently there’s only 2 official arts of her and I can’t find either of them o_<;
I heard this rendition was done by a Capcom artist for fun. Not sure which one, though.
That’s because the one guy who has them isn’t coughing them up yet. It’s not certain that the art posted above is her either. Check page 136 of the Street Fighter Storyline thread for a real but unofficial pic of her, from me, and let me know if you have any other questions about her; I may be able to help.
