Hi there! Nice, someone else from Oregon!!
Regarding your tank, I have heard many people suggest covering the back and sides with dark paper as this will help decrease the herp's stress levels due to perceived exposure to predators. You might want to consider this.
Also, I'm wondering if the hides are on cool and hot sides of the tank? It sort of seems that maybe they aren't.
Another way to help bump humidity is to plastic off the part of the top that you have the paper towels on and then wet and wad the paper towels up and put them in a hide and also on top of a hide. Living here in Bend, Oregon, humidity is a factor for me even though I have a herp cage (from Rich at RBI). I did the paper towel trick and it bumped the humidity about 7%. However, you got a good shed, so that's awesome!!
Your herp is a beauty! How old? I can't wait for mine to come but this snowstorm we're currently receiving is really putting a damper on my plans!
