all this is super awesome!!!!
i vote for UG! it will be more of a different take on a scape that emulates bsk's
are you trying to exactly copy his scape? if so there are a few details that are different about yours. if not, then it looks great, i would just maybe make the substrate line the same level across the entire front of the tank.
Thanks man, I think I might do that after all. As far as the substrate line I completely agree. It is really hard though, to get it straight, as when I do, the far right rock moves around. I have to tweak it a little more before I start anything.
