Very nice! I've never seen anything like this, especially not something where it was all self-collected.
I have to ask, have you considered adding a critter? Maybe some sort of pretty shrimp like an anemone shrimp or something else that's tiny and delicate?
Ooh, have you ever seen a crinoid squat lobster? They come in a lot of colors, but there are these two kinds that are white with black stripes or black with white stripes. They stay small and are pretty much begging to be kept just one in a tank. I don't think either of those things would eat your macros, and they're both small enough that I doubt they'd do any damage.
Just an idea...
