Vivarium/Paludarium set up- How is this?

I currently have a 20g high planted and the planted tank isn't for me. I've always wanted to do a half/half tank.. so i've done a lot of research and i've been planning the tank ever since.. here's what i have so far, let me know what you think (very rough sketches)

thanks, what do you mean by unimpeded? That water can get to it easily? i was just trying to show in that picture that you won't be able to really see the intake when i cover it with a couple small rocks. It will also be easy to maintain that way.

I wasn't planning on putting live plants in there, but the land section has larger gravel then smaller gravel, and then a layer of, what many said to use, sphagnum moss on top. Any suggestions there?

What does everyone else think?

i'm going to move this to general freshwater
