HikarenNow that you mention it, you did occasionally try my patience...
I think it looks fine.
You might need another CHE...it's a pretty good amount of space for just one. They can both go on the same thermostat if you got one with 2 plug in thingies.
This is when a temp gun is really useful. You just point it at Raf's shell and it instantly tells you the temp of his shell. The only other method is to put something about his height directly under the CHE and leave it there for an hour with a thermometer laying on it. You could use a rock, or brick, or a piece of slate.
I don't think it should be too hot where it is, but only a thermo can be sure.
So I put a small; box ion his pen ( a small one that contained a speaker; its around the same height/width as his back) the temp seems to have stabilised at 30.5 ( around 87 I think. Will that harmn him if he sits under it for ages or is it ok? id like to think he can get warm enough as the rest of it is only reaching about 18 in parts. if thats safe i will leave it where it is. Its just in front of his hide too so hopefully it wont be too cold. His little heat pad is still in his hide to, behind glass ( only about 4w)
