Yes, the people could be more blurred, but I was keen that they would be recognisable as people, and not simply become a blurred mass. That would probably look cool too and would work well in B&W or colour, but then the viewer would immediately see the dragon and identify with it. I actually wanted the viewer to see the colourful people first and then gradually realise they were blurred, and that maybe the people were not the most important element, and be drawn towards the sharp dragon, who is initially subdued by its lack of colour.
However, the people could still be a bit more blurred, without compromising that idea.
