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.
Of course, I sometimes branch out to things that aren't books. A while back I tried my hand at creating some photo-realistic fantasy art to go along with one of my favorite series. Here's the result.
I worked on a couple of movie posters for Clockwerk Pictures this week. Fun stuff.
