Many consider pixels in a negative way: out-of-fashion, imprecise, too basic and not professional. On the other side, there's even who 'praise' and promote this style, appraising the strain necessary to "synthesize" reality. Consider the four examples above (representing: a secretary riding a (Vespa) scooter / smokin' break / taking notes, on the phone  / stretching her numb back). All the four drawnings are easy to understand and it's simple to distinguish the human figure, and still, face is made with a couple of pixels, just like the neck... For people (like us) incliner to an hyper-realistic kind of representation, this style requires a synthesization strain. There's not enought space to drawn all the details necessary to recognize a well-determined shape, so we create a sort of "visual average" which, seen at the right distance, suggest the right idea. To get everything harder, we've used an 8 colours scale (plus greyscale), so that we couldn't use the right colours (notice the magenta for the skin). A clarifying example: who knows theese two models, immediately identifyes the two cars, even id they're practically "detailless".
