Gohabs93, My self and several people from another car club that I am a member of have had some problems with Teespring in the past few weeks, I would do a trial order for yourself prior to selling the shirts as most of us ended up opening a paypal dispute against teespring. We all received our shirts but the prints were no where near what was advertised. They do not make the print bigger when the shirt gets bigger.. so although it might look like the image provided on a small sized shirt as soon as we fell into the Large or XL size the graphic became too small for the size of the shirt and made it looked out of proportion since they didn't upsize it.
However your graphic is much different then the one we were using and might not look soo bad even if the print doesn't get better. I like the designs, good work!
