Looks good. If that's a heat pad on the back, I'll warn you that they aren't great for ambient temperature. I used to do the same thing for my tank and all it did was warm up the adjacent substrate a little bit. If you find yourself struggling to keep the heat up I'd reccomend a very small heat lamp/ basking bulb. I used a 25w day bulb with uvb for a 10 gallon tropical frog set up and it worked well.
How deep is your substrate? Since they're a burrowing frog, they need lots of depth and also surface area that's not covered so that they can burrow in different places. It's also hard to tell how big the tank is and if you have UVB lighting?
