Zarkonnen, i know it is a fair thing to put out a payment offer, but for crying out loud many people on the forums would be alright with creating artwork for you, for free!
(Mostly because drawing is something we all do in our past time to an extent.)
I do not mean to be quite so pushy, but why do you not just ask around the forums? Create a topic which would attract more people up for the job whether you pay or not.
Heh, I did put it everywhere else but not here, that's true. Gonna put up a thing now.
But I do absolutely want to pay whoever ends up creating the in-game art, because to do otherwise would be pretty unfair!
But, some of us do not want to be paid.
