I'm always worried people will find Chezawoofs design to be so horrible they'll decline, or that my idea would be too freaky/weird for them to feel comfortable with drawing it x-x' Not that I've ever really had any weird ideas. I guess the "weirdest" one is that one I haven't got yet, but that artist kinda specialized on that particular subject, so not only was it completely fine and accepted, but also very much appreciated since people apparently didn't commission them for that all that often.
In this case I'm going to go for near-total artistic freedom tho. Because sometimes it's nice with a little surprise. And many artists seem to appreciate getting to decide what they feel like doing.
