One of the main issues I see is the substrate, it needs to be removed asap! It looks like the corn cob bedding, which is VERY DANGEROUS for dragons. Actually all loose substrates pose a serious health risk, (impaction) which can cause paralysis and, or death.
Rough textured floor tile is my substrate of choice! It is easy to clean, doesn't harbour bacteria an mold, easily disinfected and keeps their nails trimmed nicely. Others you can use are nonadhesive shelf liner, paper towels, news print or, vinyl flooring.
An elevated basking area (climbing log) would be a good addition so he can get closer to the lights by choice. They love to climb, lol!
