I have that, I was looking for something in an image format so that I could begin work on the overlay. If there is a way to go from one to the other I wasn't smart enough to find it

I did contact Game On Grafix and they were good enough to send me a template. I uploaded it here if you want to have a copy. Much thanks to Game on Grafix! I was planning on having them print my artwork before but this certainly sealed the deal for me.

As for my art direction it is horribly bouncing back and forth. I started a Gauntlet theme, I also created most of a Robotech theme as well as tossing around several other ideas. I think in the end I will go with the Gauntlet, but if you ask me tomorrow that might have changed!

What ideas have you been considering?
