Honestly I think it's way to busy and takes way to much away from all the work you've done on the background.
What you had before was nice.. I would say if you could say take the diffrince between the two you would really make things look nicer.
You did all that work on the back ground that is truely amazing. I never even though of trying something like that till I saw this. I want to give it a try my self once I get my 75G to replace my current 50G. And I think while, yes it's a background. You put to much work into to just cover it up with plants.
Regradless. VERY NICE
