Nice! I really like the way the light from the portal is reflected off of the floor tiles. I also like the tile around the top of the vital apparatus vent. The one thing that could make this better would be to only give the vent one shadow, not two. Two shadows doesn't make much sense because all of the other objects don't have two shadows. This might be solvable by adjusting a light or something. (I'm not exactly an expert in Blender)
