My votes are for #3 and #9. Those are crazy amazing layouts! I love how deep they are. They remind me of standing in the valley of a canyon and looking up to the hills/mountains/jungle. The mosses in them are incredible. Makes me quite unsatisfied with the simple layout of my own tank.
I'm not a huge fan of iwagumi layouts, but #2 does it quite well, in my opinion. The scale is impressive, and the whole thing has a very "old" look to it. I think the "grass" is well done.
The winners deserve the praise!
