Not exactly what I wanted

So this is my first time posting something like this, but I've been working on a pallidarium for the past week or so and I know it takes time and skill for a palladarium to be the way you want it to be. But what I wanted was a floating platform that takes up 1/3 of the tank and I wanted more plants at the bottom of my palidarium and I feel like I don't have enough plants either. So I wanted to come here for some advice on what kind of plants I can put in here

And before anybody ask yes I got animals in there. I have three nutes.
