Ok, I've always liked your scapes a lot, but there's something about this tank that bothers me: the fact that one side is all wood, and the other is all stone. Kinda like an asymetrical symetry...It doesn't look too natural to me. But apart from that, the tanks looks, in true UG fashion, great! I think the stems look awesome, very light and airy indeed. As for the Nymphea, it looks stunning. Source has gotta be the first tank I really like without liking the hardscape so much.
All this, of course, coming from someone with a lot less experience in aquascaping.
