i freakin LOVE this cover! No photoshop in sight! An actual drawn, painted cover! So refreshing!
Actually it looks like a digital painting to me (the colors have a very computerish smoothness), and I gather that Photoshop is one of the most popular digital painting programs in use these days. So it could be Photoshop in the literal sense, even if it isn't "photoshopped" in the vernacular sense (I guess the program's functionality has expanded since that term entered the vernacular).
