Ah ok, as a french man, I know almost nothing about wrestling.
If you have any suggestion about a suitable backcover background picture, I'll replace it.
By the way, some comments about your Spider Man cover.
1 - Nice Front and spine good as they are in my opinion
2 - On the back, text is still too big as compare to screenshots (screens should be at least half of the space)
3 - Marvel and activision logo are missing
4 - NUS number, barcode, are not updated
5- the backcover background is better, but it should be even more "orange/yellow" (play with the color levels in gimp)
6- maybe bold text or shadow behind it to make it more "readable".
Those are only my personal opinions. Good job anyway.
