This is the livery for the AirTran 737-700, converted from the Zibo version (by Jviation) to the LevelUp. The Photoshop editing was crude, but the plane in the sim looks beautiful. Next, I am thinking of adding the interior seats and other misc items (lights, announcements, etc.). Let me know of anything you would like for me to add.
(p.s. I tried configuring the plane as best to how I remember AirTran 737s looking like in the cockpit. Not saying you should stay on this .cfg file if you think different!)
