What kind of fish are you planning on keeping? That question determines a lot of the feedback you will get.
For example, if you plan on dwarf cichlids like my Apisto Agassizi, that isn’t enough cover as they like and feel safe with lots of plants and things to hide amongst. My bbs love the two red tiger lotuses for this exact reason!
Other than that, I do think it looks great! Could use more plants in the surrounding areas but I’m biased because I’m a gardner both in and out of water lol
