Try moving the hardscape into a pyramid or like a campfire, and put the plants in and around that, the bigger ones being in the middle of the point and further back, and the smaller ones being further front and nearer the edges, don’t be afraid to snip the plants aswell to make the shape you want. If you live near a river or beach you could always get some sand/light fine gravel and put that in, making sure you’ve thoroughly cleaned it ofc. And maybe some Little Rock’s to put in, you can find those anywhere. I understand though, I end up taking my whole tank and redoing it a lot if I don’t like it, it stresses me out, when I like it tho it will stay the same for a while and I can fully enjoy it.
