I think you should add more water to your tank. I cant see any of your plant from the photo. And it doesnt look like a planted tank to me.

You should get some plants that will grow from the gravel out of the water (I believe they are called emmersed/emersed?)- I think that would be cool. Also, it'd be neat if you got a little more water and you could put in some feeder guppies and watch the turtle chase them around.

I also feel this tank could use some plants growing out of the water, I do like the rock and general layout, but it looks like it needs something.

Hmmm, I had a turtle for a few years. They are wonderful pets with proper care. I would recommend higher lighting, deeper water and some more plants. Maybe frogbit (a floating plant), java moss, and some hornwort? I know turtles/terrapins like your spotted will eat most plants. Anyways, higher lighting. I would go with a cheap set of T5HO 24-48 watts, it works great for both plants and reptiles. And ultimately you will need a larger tank, spotted turtles get quite large and unruly. They also love to mill around in the dirt. I would try to create some sort of land area for him to crawl around on. Good luck. :)
