Nsa build with enough fish habitats

[The_Shrimper]

Hi everyone!
I'm trying to build my very own nsa, and this is my progress so far.
I'm building it for the Redsea Reefer 200xl,
Which is basically a 40 gallon cube, which will host lps and softies.
My concern is about the lack of fish hiding spots, any suggestions on how to add hiding spots and still make it look kinda in the same design ?
Thank you?

I would build up the base of the main structure with some smaller pieces to make some smaller holes/caves or have a little overhang just an inch or so above the substrate hanging out from the main structure stretching out between the two islands. You could also make the smaller island a little bigger with some holes/hiding spots.
