Is khal drogos dorsal crest being burned from his basking light?

[Rbalenbin]

I moved his basking light up 2 inches (it's a 40w incandescent bulb) just as a precaution until I'm sure he'll be okay. I attached pictures. He's roughly 10weeks old now

He looks fine to me.
You want about 10'' away from the basking bulb
