you're right, i think my tank will be mirror image of the finished pictures.First off, those are some awful nice pieces of wood you got!!
I suppose you could make something like that out of it.
Your wood seems to lean the other way though so you'd have to turn it around I'd say.
To get dense growth like that you do need pretty strong lighting and co2 input.
As for the stems in the back:
also, they probably did make the substrate a little thicker as well to let the stems take root properly and dramatize effect.
