Looks great now! All i'd add it to make sure you've got a thermometer and hygrometer! also if you've got hatchlings watch their feeding to make sure theyre not swallowing too much of the substrate. Theyre clumsy little buggers!
Oh and wheres the waterdish?
you want your temps between 70 and 80 in the day, and 60 and 70 at night, as a rulew of thumb. A little either way and you're fine. If your room temps are only 55 and 60 then yes i'd use a mat. I have 1 that i use only in the winter, in the summer they really dont need or like it
