It very well may be the camera angle or just me even :) Just keep an eye on it and see if anything changes or you notice it yourself. Better to be safe and on the lookout than sorry.
I just noticed you have a red heat lamp in addition to the normal incandescent bulb. Generally its not needed and you want to make sure it doesn't get too warm in there.
Welcome to the forums! There's lots of great people here who are always willing to help.
Your new cham looks great and the enclosure looks awesome. Where was he purchased from?
Use light your reptiles or the reptisun 5.0's. Most definitely use linear bulbs spanning the length of a cage that size. I would even use a dual bulb fixture so there is added light. Something in the 6700K range color wise.
If you are going to use melamine, I would make darn sure you seal the ends of it. It is not typically plywood, it is pressed wood and when it gets we it swells.
Hey it looks pretty good. I would reccomend adding another plant to it though for more foliage for you new friend to hide in. That Schefflera looks pretty thin to me.. Maybe even adding another vine or two for a little more horizontal perching spots.
Looks to be a male when I zoom the pic in, but still hard to see. A better shot of the back of his rear legs would tell us more as others havel already said.
