That's actually very good. Overall, it's clean and you can tell that you paid attention to detail.
Personally, I'm not sure how I feel about the word HOCKEY being on the spine alone, I'd either have the whole title spelled out or none at all.
There are a couple things, though:
-To the left of the main image on the front, there are some remnants (from what I'd figure is some leftover from erasing stuff)
-The Genesis logo and seal are lo-res (Look at BadChad's Genesis template for hi-res stuff)
-The 16-MEG image and ESRB stuff is lo-res too. I'd figure there's some resources out there for the ESRB, but that 16-MEG thing would have to be rebuilt.
Bring on more stuff; it's always nice to have another talented artist.
