In my experience, improving in 3D alteration is easier and faster than in the more complicated creative work Ira is talking about, but the main point is the same: Dont get frustrated because your first cards arent as amazing as you want them to be

You can choose to sell your goods on the eBay online marketplace for a set price or in an auction where consumers "bid up" the selling price
