very nice, you've given me a great idea for the background of my 90 gal tank. Mines also going to be done up green, but with fake plants (bloody silver dollars). Looks great, and very natural.
Looks Really good. You have obviously put alot of though into it but I actually prefer it at the beginning before you filled it with plants. I think you would have done better to just get one or 2 tall plants, such as some vallis or something similar, Would have finished the tank off nicely.
I think its a shame you've covered up the lovely bogwood and background with lots of plants.
