Nice job!
It looks like you might have 3-4 spotlights on top in addition to your long tube UVB light. Regularly one will do, and Quadss like it cooler, so check your temperatures across the top levels. I would guess unless they are all low wattage, the top of the cage might be too hot.
Quads are one of the most contrasting color species, with a dinosaur appearance, one of my favorites. With quads go lighter on supplementation, if you follow Panther and Veilds supplementing schedule, you will typically see edema, fluid pooling under the neck.

CHEERS!
