Oh wow what a great change! It looks so good! My only suggestion would be to move your heat lamp over to one side. You don't really want it in the middle like that because it may not provide a proper temperature gradient. Just make sure your temperatures are correct though and it should be okay. The cool parts of his tank should drop down to about 75, so if you find with the heat lamp in the middle, it produces too much gradient heat and makes the whole tank warm, you'll want to move it over to one side to concentrate the heat on side, allowing the other side to cool off.
What
UVB light did you end up going with?
