Hello looaks !
I really like the character. A bit less the environment. It feels really 2D, flat, and dull for a lot of reasons.
I tried some things very quickly, as usual it's not production quality, but food for thoughts. Tell me what you think.
1 • Add some "floor". It gives some perspective, a better sense of 3D, and a much more readable scene.
2 • Add more lighting. Make the room physically exists, with windows, lighting, exits, etc... Try to make zones & paths more unique using colored lighting & different lighting sources. It also helps with player orientation, it's much easier to remember a room this way.

Bonus comparison shot :
According to me, it has better atmosphere, is easier to read and easier to remember.
You don't need to make things as drastic & dramatic as I did. Subtlety recommended
Hope it can helps !
