Just grow a nice green carpet and I'm sure it will look 100 times better.
Remember not to bury the Buce's rhizomes, just like you wouldn't with Anubias or Java Fern. Burying the roots to anchor it, is fine.
Is that Blood Vomit? Pretty sure that will die without high light, ferts and co2.
The big black rock on the left looks too unnatural. The color of it can be worked with or as algae and biofilm builds up on it, it will blend in better, but just the angling of it, just makes it look too unnatural. Just my opinion though, and I am by no means a skilled aquascaper, not even close haha.
