Can someone edit the first post here with a list and links to all of the retail covers created and /or add them to the site?
I messed around with some of the TMNT covers and improved them (I think). First I took the retail version in this thread and fixed it a bit (better blurring between back and spine, removed part of the non-retail Ultra logo that was still visible on the bottom of the spine, fixed the "holes" in the screenshots and added the retail spine white lines).
Here's mine:

Then, I thought it would be cool to have a retail-ish version of Shenske's newest cover where he re-colored the turtles to be more like the cartoon and the toys:

While I was at it, I used my changes to improve (in my opinion) his TCP-spine version of the cover (with the "Nintendo Entertainment System" banner on the spine). Basically I used my version above and just pasted the NES logo back onto the top of the spine, and added a small Ultra logo to the bottom of the spine that doesn't cover any artwork.

Anyway, here's all three in a single zip file. Tell me what you think.
