The original concept sketch from the designer of the new Daleks :
The concept looks more like a Dalek-as-we-know-it with extra casing elements, an all-in-one bumper/skirt extending up the back of the Dalek and linking to the shoulder section. The domed panels seem to be raised, more like armour. The back “vent” looks to encase the machine beneath, not be integral to the body itself – and so on. Overall the geometry is still “Dalek”, most crucially there is no actual hump-back, just extra armour around the midsection.
It’s a shame that what we actually got was this :
I can’t help but feel that if the props had been built exactly as per the design sketch we’d have got some not unreasonable new Daleks. Not everybody would have liked them….
BUT…. at least they would have looked like “real” Daleks….
