do you plan on making these for TTM?
I like all the designs as they are, except for the triple autograph. IMO, you should try to add some kind of texture to the black, so it isn't simply a solid color. Also, I think the that the YOUNG GUNS name would look nicer with a different font - something more stylized. Try dafont.com for picking up new fonts, otherwise if you are going to use Photoshop, I suggest you try something other than a basic font.
BTW, I don't know if you view the basketball message boards on here, but I've been designing a bunch of cards lately and posting them on the BKB boards and my blog.
Here are a few links and images to what I've done, based on 90's styled inserts:

They are sweet as! Love the 90's feel about them
