@Sluggo---Don't take this the wrong way, but as I was scrolling down to read the posts and came upon your cover, the top half made me immediately think of Mickey Mouse due to the placement of the circles in the top corners. I think it is because of the size, shape and position of them. Perhaps you can do something jagged or a different shape to throw off that perception.
It could be just because of of the scrolling that I perceived it that way, but I wanted to make sure that I mentioned it.
Please accept it as constructive criticism and just my perception. I do like the cover.
