As I scan the 'top stories' list of the novels here on Tapas, I have to say that the covers all tend to have a particular 'look' to them. Most of them are very clean, very professional, and leaning toward what is typically called the 'shojo' style. Is it essential to have this style to truly do well here? I know I'm personally rather fond of the cover I drew, inked, and colored myself, but it definitely doesn't seem to compare to the pros.
With that said, what is a good way to commission professional cover art complete with high quality ink, color, background, and lettering? And what would be a reasonable price for a single piece (with the additional allowance of the visual rights remaining the property of the artist?)
