Hello,
I would like to share a project inspired by Star Citizen and Subnautica I’ve been working on as part of my learning experience with Unreal Engine and improving my environment art workflow. There are still areas I’d like to improve, but I learned a lot from the process.
The full project on my website at

I think it needs more visual story-telling to explain how it's underwater. The "windows" don't look like portholes into watery views. The floor could use puddles of water, the walls could use leakage stains, drips might help, lighting could use god rays with refraction patterns, etc.
I recently checked out one of the Naughty Dog environment artist portfolios, this might give you some inspiration for how to achieve the "underwater" look.
