I like the first image of the three best but not a whole lot, Clark. I think you need to find someone to make your covers. Check out my covers and if you like them I'll put you in touch with the guy who designed them for a hundred a pop: http://www.amazon.com/Eric-Christopherson/e/B0037GOO9W
Otherwise, I'd keep hunting for a good book cover designer...
I checked out your covers and they look really good. I'd certainly like the contact info for your guy as I may need him.
Sure, it's Bradley Wind, who can be reached at: firstname.lastname@example.org
