This is looking very good! Doing without the rafts gives it a different look from the other ripariums we see here. Just one more variation that demonstrates how flexible the whole concept is. Hydrophyte does such a beautiful job with his ripariums it is always tempting too assume his is the only way to go, but you are proving that not to be the case.
But, I like the rafts because they let me use so many other plants in my ripariums. My "collectoritis" disease drives a lot of what I try!
