Somewhat overboobed (It's cool, but you're trying to be an ASSASSIN, and even the comic artists mess up sometimes.)and the hair is a bit too red, it's not really supposed to be dyed. (Or IS it?) If that's all I have to say about it, you can be reassured that your costume is awesomazing.
I would love to do a few paintings of you as The Black Widow,if you can send me high res photos that aren't copyrighted by photographer,I can work from that,I'll give youoriginal sketch as payment,promise!
