I think that you are off to a good start. Personally I would move the driftwood a little to the left or right. Even though the wood's shape is asymmetrical, putting it in the center is creating too much symmetry.
Looks good, I would also move the DW one side or another and then I would add a black background cover to the back of the tank it would really make the colors of your tank stanf out.

Yeah, I am going to move the dw over, and definately adding a black background, the one I have now was the one I had before with the fake plants and ornaments.
