Giedi Prime house harkonnen

So it's been forever since i read the original Dune novel and I don't really remember if there was an exact description of what the planet looked like but I was loosely trying to make this planet look like what I imagine Giedi Prime to be, an industrial world mixed with crowded living conditions and a polluted atmosphere.
I drew inspiration from the planet Illium in ME and Coruscant in Star Wars (which are basically the same thing anyway).
