I think after much deliberation I want it to look something like this:
Red is the lotus, dark green is Christmas moss, and lighter green is dwarf chain swords. I wouldn't mind getting hand on a couple rhizomes of anubias nana petite to stick out the twisting parts of the driftwood in the middle.
I *think* this plant is pygmy chain sword:
I'd like to separate this pot and spread it to begin a carpet, maybe order a pot or two online if I need to.
Lastly, the cholla wood I mentioned before... I don't think it works to just lay down but considered doing some sort of 5 stump formation. I'd cut the cholla wood into smaller pieces and stick them out of the substrate. I could either make a semi circle where the middle one is the tallest and they get progressively shorter around the circle, arrange in a flower type (think like a daisy) with different heights, or just nothing at all. I'm not sure I like it but then when I imagine it all filled with the chain sword it kind of breaks up the grass field effect.
I could put rando stumps throughout the carpet with logs sticking out diagonally.
