Optimal King Setup?

[Derek1]

My King stays burrowed 95% of the time. Here is my setup.

29gal tank
Aspen Bedding
Under tank heat pad (not thermostat controlled)
Top light puts out no heat
Large water dish
Hide is on the heat side

My setup and look is pretty boring and would like a better looking display. Is there something I should change to make her more active? I'm more concerned about her health and don't want to change anything that could endanger that, but improve it. Here is a pic.
