Brandon,
Most of your uploaded images would not be printed by FAA, since they almost all show borders, backgrounds, some crooked, some with shadows,etc. I would try and get better images of all of them and re-upload the new images, if you want sales.
There are many tutorials on here, how best to copy your artwork, here's mine:

and you can visit my site here and under "Photoshop-Not for Sale", see examples of how to make the stuffyou need to create a good and cheap copy set-up,
