I make covers. I have created hundreds, probably thousands of books. I know about books. The most important function of any book cover is to make a reader pick it up. It's a game I play... What can I not resist? That's what you want on your cover.
I've always wanted to attempt some photo-realistic fantasy art. First attempt. Not quite finished, but thought I would put up what I've got.
I wanted an aging warrior, wizened, with a story in his posture. Is the dragon his companion or about to pounce? If so, does he know it's coming?
Just added the "Cohen the Barbarian" on a last minute whim. It won't stay. If you're a fan of Terry Pratchett you will be familiar with the octogenarian hero. This would be him a few years earlier, maybe just before he lost an eye.
