Oh my, what a beautiful little Halmahera Indonesian (Tiliqua gigas gigas) you've got there! NICE!
Great set-up. Most of us achieve the wider temperature gradient by placing any heat producing bulbs or mats on one side rather than the middle, so we can get the cooler side down to mid to upper 70's - low 80's, while still offering a warm side in the 90's (preferably with a basking spot in the upper 90's to low 100's). And it's always great if you can offer more places in different temperature zones where they can feel secure while still thermoregulating. So another hide or two wouldn't hurt. Or deeper substrate if he likes to burrow.
I would also eventually do a larger water dish, one he can fit inside in case he's one who likes to soak, and it also helps raise the humidity --Halmaheras often require very high humidity, like 70% or more.
Good luck with him! How is he so far?

. I am very excited about this and cant wait to show him off. I don't know what kind he is, so if someone could help me out that would be great. Overall he looks healthy, but is still very stressed out form the reptile show I went to. I think he/she is about a month or two old. Well anyway I can now show off my new skink just like the rest of you guys 
. I still need to figure out how to post pictures onto this forum, so I will need help with this also.
