As a writer of fantasy, I would love it if my book had one of those beautiful painted/drawn illustrations on the cover. Mostly because I'd like to see an artist's interpretation of something that happened in the book. Those are my favorite moments when I can look back at the cover, after having read the book, and think 'hey, I remember that part!'. Unfortunately, it seems like the majority of book covers today resort to close up shots of objects or silhouettes.
