The concept art from Jadorowski is also pretty awesome and is even more extreme than the Lynch designs, and tbh I feel Dune should have been far weirder given it's so far out in the future. The only thing I kinda like is the Harkonnen design making them look like mole people (then again Jadorowski wanted Feyd Rautha to more or less be like a future style David Bowie which would have rocked on the big screen).
