They look great!
The Java fern (3rd pic down in your last post has a closeup) needs to be tied to a rock or wood....and not planted. The hard stem like part (rhizome) will eventually rot if you leave it planted.
Anubias should be tied to wood/rocks also.
I know that will disrupt your layout, but maybe you can use a small rock or stone and have them on top of that.
