Some textures, especially the crete_ and tnnl_ ones on the floors, are bland, something with more detail and dirty looking will look better.
Control room and stairs leading up to it are too small/narrow and not very nice. Would be more interesting with a bigger control room that overlooked the box machine room.
Scrolling sky fx looks trick but isn't very noticeable.
The corridor at low level between the crate storage and machine rooms is too long IMO.
The rooms are pretty big but the map feels a bit limited in where you can go, could prolly do with more paths between the rooms to give players more options.
The molten metal looks very nice and i like the idea of using a conveyor to get around the map, saves me having to walk
