Its either my eyes or you are shaky with your photos...ask the rocks not to move and try again...just kidding looks great.
I have the original build on YouTube if you want to somewhat create the deep cave we did at the warehouse.Below is the link check it out,hope that helps a bit.
I agree with Kein on those corrugated conduit piping as I am using them for my lights wiring.
I feel a little different on the amount of rock than some other folks not that I am creating a crazy discussion simply from my own experiences.
I always believed for best filtration is as natural as possible with a little helping hand from Carbon and a reactor or dosing and as a main filtration would be the amount of surface created or placed in our little boxes that creates all types of pores (macropores, mesopores, micropores, fracture, vuggy,...)
There is no man made surface that is created for our hobby that contains all the surface require to carry a vast array of filtration bacteria than the rock we place in those boxes.Yes all rocks are not equal as some are heavier than others for a reason (Rocks normally decrease in porosity with age)
When you go diving most of the fish we have in our aquariums are in or near the rock work be it for shelter or food. In my case I have over 120 fish and counting without any loss or damage by picking or fighting for a hole to call home, and I still believe my system is empty.
All aquariums be it fish or reef setups are beautiful in my eyes simply cause the owner love what they are creating but with every design consequences arise,...
