I absolutely suck at aquascaping

Thanks for the feedback and info.

All of the rock is same, Marco Rock. I actually wasnt sure what it exactly was until few days ago. I went into J&L, as I knew they had Marco rock, so i wanted to compare it to what I had. Turns out what I had is Marco as well. I heard a lor of good things about it, but truth be told I am disappointed in it. it is so bland and dense, nothing like real reef rock.

I do have quite a few big boulders, and I did use them as base for both structures. I also did drill bunch of holes and used fiberglass rods in there (orange driver markers) to connect quite few pieces on the right hand structure. I only used about 50% of all the rocks that I have, so I have more than enough. I will smash 1-2 leftover boulders into smaller pieces to see what I get randomly.

Plan is to connect some of the pieces together with cement, but 1st I need to figure out what scape I actually like and want to keep.
