Does anyone know how to get better engagements on this site? How do you promote yourself?

2. Always put minimal price 1-5$, not more, unless you're a popular artist with big attention to your auction, you won't recieve any starting bids and site will automatically put you lower. Sometimes you'll have a winner with a very low bid, but most of the time there will be people to bid more for any bonuses you provide (like style changes, additional character versions)
