I'm no guy - but what the heck! :-D
I really dig the back and the inside... you've chosen some fantastic photos!! Now the front, in my opinion that needs some work.
Use just one photo, the way it is now it looks a bit muddle. I see that you used the same shape one both front and back - good thinking! But what if you use it to put the title on, instead of the photo that imo doesn't add anything to the cover. (if you try this - you can also loose the outlining on "one night in vegas" - which right now just make it difficult to read).
