Oooh, that's a mighty nice sketch. the perspective's very good, but I'm not sure if it would work on the shirts. It seems to print in 1x1mm dots, from looking at the previous shirts I have (Utter Pirates had lots of little specks around it, but they came out as 1x1mm dots).
I was thinking perspective more like this. Also, I love the font for CARELESSAIR, but Aeriel Piano Removal Specialist couls use something else, something san-serif.
I'd buy one of those. I'm definitely a fan of the careless air shirts, and i'd definitely rather have that on a premium shirt (like a nice work shirt).
You can't use the TG logo as Quiky said in the first post, because of copyright issues. The FG logo on the other hand is fine, and Ice has provided you with one.
