I personally like and aim for kinda natural/after storm look so i have lots of debris rock scattered throughout my sandbed and a few pieces that are leaning on each other to get archways
I think it really looks good. Are you planning a major overhaul? Adding/removing rock? Oh yeah, is that a peninsula? Can't really tell from the pictures.
Just a thought, I noticed the two main scapes are quite level from one to the other, if you are adding more rock or just adjusting the ones you have already got, you could put a bit of height to the rock scape on the left so that it does not have a formal look.
