ill be honest...the tank needs a little more work. try sticking with large rocks of the same color(either light or dark)...having a lot of different shades of color will break up the main theme. also a background is always ideal. maybe try to find another piece of drift wood to add with the one you have...instead of laying it flat with the rocks, position it as if its comming out to you or jutting upwards. these are just things i would do
