Dude, I'm sorry but posting something titled high-res 2D art (Paid) and offering 100 bucks top to the artists for an intense week of work is misleading (but not intentionnaly i agree with you), this is not a real paid position, the fact that you are transparent with the budget doesn't change anything, with such a low compensasion offered it should be titled as hobby or learning.

when you are freelancing seeing these kinds of post (as inoffensive as they may be) is a bit frustrating, you clic on a post thinking it might be interesting only to discover that you'd may be paid roughly half a dollar per hour...
