Very interesting approach. The feeling I get is of a quiet lake in a forest. They tend to have a lot of moss covered driftwood and sunken trees in them. It takes me back to the days of fishing in the UP of Michigan as a child.
The only thing that I would do to complete the tank is add something to the substrate to fill it out. Whenever I see bare ground in a planted tank, I get the impression it is not finished. I'm not sure what would complete this picture, but anything from crypts to hairgrass come to mind as possibilities.
Two 1 GA desktops, a 5 gallon, a 2.5 gallon, a 10 gallon, a 20 gallon, a 25 gallon, and two 75 gallon tanks, all planted.
I am an expert on algae, so ask me if you have questions. I know how to grow it, just not how to get rid of it.
