Few issues that I see. If cloth is representing length and width of your tank, your scape is way too close to the edges, which means it will be way too close to the glass. You wont be able to get magnet in there to clean glass properly. Also, unless you have lots of water movement, all those alcoves will get detritus buildup inside them, and will be pain to clean up and suction out of tank. While it may looks cool, there arent that many hiding spots for fish, which is one of the primary uses for scape. You want to give fish room to hide if they need to. Finally if you plan on having SPS on the right side, you want to have height of your scape be at about 1/2 the total height of the tank. That way there is enough room for corals to grow up (ex: 24" high tank, height should be about 12-14" for scape)
Looks good! Only things I see: the structure on the left may be a problem with its proximity to your glass, and also fish hiding spots. The detritus issue would only be an issue depending on how you set up your power heads.
that’s said I’m a newb so take what I say worth a grain of salt lol (didn’t mean that to be a pun )
Looks really good! If space is an issue, maybe scoot the two main structures together and center the whole thing? Also curious - what varieties / quantities / options of rock did you buy (if you don't mind sharing)?
Please post more pics when you get it in your tank!
