The back looks really bland, but both front covers look really good. Keep up the awesome work with these Saturn covers!
One question though, would it be possible for you to start making covers using a Japanese style cover template as well? I'm guess I'm not in any hurry to put any of my Saturn games in DVD cases, but the purist in me cringes at the sight of Japanese games shoehorned into an American cover template.
I used to use the Japanese style back when I was trying to make covers for the Slim DVD Saturn project. The reason I turned away from it in favor of the American style is that I plan to also amass a Sega CD collection at some point and I'd like the two styles to mesh.
What I used to do while I was still printing covers off in the Japanese Slim style but people started doing American style was copy a large part of the front image (enough so it would scale proper) and do the same with the back image. Only did it with a few, but it usually worked great.
Edit: Oh yeah, I was actually making the cover thinking that MMX3 actually came to America. Turns out it did actually come to Europe though, although I have yet to find a European copy (and I somehow bet it would be enormously expensive).
