Don't hate me. I tend to speak what's on my mind.
Looks like a bunch of rocks strewn about. Some go straight up, some left to right, some front to back. I don't see a natural flow.
I would try to group them into something. It looks like you have some real nice ones there. And maybe take one outside with a hammer (and the appropriate safety gear of course, or a towel) and whack it to make some smaller pieces you can lay around the bigger pieces.
I'm new to
aquascaping, but probably have a hundred videos under by belt
And yes. Use a plant to hide the hose. That rocks looks like an accident waiting to happen.
I saw a video just yesterday of a Tuber creating a
cave with large rocks. He mentioned not to place the rocks on the
sand as the sand could shift over time. He used a couple layers of that thin, white wrapping foam on the bottom of the tank, built his structure on that and then added the sand/substrate.
