No problem. At the start, I'd recommend starting low with your pricing. Your artwork is good, you just need people to see it. Starting low is a good idea, but the moment someone notices that there is a price tiering and the prices are huge compared to starting bid, they leave. At least, if the artist is new and doesn't have a wide portfolio, in my experience. I'd say for starting out, set Autobuy to include everything you are willing to draw for the character you are selling.

Having AB be $20 LESS than the first extra is... a bit much in my opinion.
