Underwater Lab Background

Working on a background for my streams. I dont know when I’ll finish this, but this is about 2 days of work so far.
Its going to fishing swiming in the backgound, a couple fish tanks, I wanted to add a claw machine in the background (those purple cases in the back). There will be a couple of plant-based tanks on the upper floors. The person shapes are height references for when I build it, so I can acurately match the right size without walking your head into a ceiling.
