Hi there
Before I answer fully here's a little tip: Telling an artist he makes: '…good lack of concept artwork…' is NOT a compliment!
As for the rest of your 'request'…so you want me to draw Betty and Benny Boop and put it in YOUR DeviantArt gallery…for free? And then you tell me, rather than ask me, to sign a petition!?
It would appear that you and I have very different interpretations of the word 'request'!
So it is with little regret that I will have to decline your 'request':
I have no interest in drawing other artists characters.
I don't work for free.
I don't particularly like Betty Boop (and even though I'd never even heard of her estranged father, Benny Boop, I don't like him either!)
I don't sign petitions when ordered to!
