Looks great 8/10.Maybe add some more stuff? It looks a bit empty.But great use of the Content Fan.
too empty
The top looks a little to flat. :/
too emptyOn real oil rigs, there about 1 meter squared of empty space MAXIMUM, usually in hallways.
Needs more stuff. Add desks, offices, a second floor to the box-house thingy and such.That's a completely random guess, and a hallway would take up about 3 sq. metres.
