@big brother: I tried it, but I don't think it's an improvement over the original version. I might need to either suck it up and do proper between frames with the lighting and everything or just be happy with the current animation. I want to animate a lot of tiles in this game, though, so I don't want to spend forever on each one.

Also, this atmosphere is much closer to what I originally envisioned for this area. I was really dissatisfied with the original on both a technical and atmospheric level, which is why I decided to redo it.
@Demian: I can move it, but the idea was that the monitor was supposed to be displaying a readout for the pod. It doesn't look very integrated, though, so I might try a different monitor design.
@trough: Yeah, his was really smooth, but something that smooth would have looked out of place with the rest of the tiles, so I tried to take the general idea and do it with fewer colors.
The idea with the rivets is that they're there to add visual interest to the floor. It's hard to make things look correctly scaled at this size, so they'd be too invisible if I made them smaller. It's not 100% realistic, but I think it looks nice. Good point about the grate; I can add a border.
Edit: Okay, I fixed up the tank.

Better now?
Edit 2:

Does this look done?
