Well thankfully there is a lot of guys that I deal with who do the piece and then let me pay afterward so if I didn't like it I wouldn't have to pay for it.
I had a guy draw me a Punisher and Jigsaw sketch way before I started getting into art and I kinda forgot about it and eventually threw it away because it got ruined. Wasn't that good any how. But recently I sent my book to a guy (this was bout a year ago) he sent it back with the Punisher chick, Puny sher, and the Punisher van sketch and truthfully I didn't care too much for any of them but they were still Punisher and I paid dirt cheap for them so of course I kept them but oh well.
