Not really liking it. I don't mean to offend you but...
1. You have bad renders that are pixelated, your back cover needs capitalization.
2. What is that stuff on the bottom of the back cover?
3. I highly recommend should use a 360 template from the resources section.
4. How does burning Moscow to the ground "wipe FREEDOM all over the soviets' faces?" There are too many plot holes in your story.
5. If you are using MS Paint, see if you can get GIMP. It's free and easy to use.
