John, those images are striking and very effective.
I think there is a lesson to be learnt here - it's not what looks most realisitc, it's what looks most effective. Johns images are a long way from looking realistic on a purely scientific level, yet somehow they achieve a 'realism' that's much more effective.
The choice of colours potrays the image in a much better way, making it easier to understand.
