I suspect the way the page is displaying the pixel is creating a blurring effect. I work a lot with unreal engine 1.5, and do a decent amount of work with pixels (for instance, I maintained 4 or 5 minecraft texture packs for a long while) so I can spot clean pixel vs blurred pixel a mile away. It is very good, but the blur (although I'm sure, unintentional) I think kills things a bit. The palette is also very interesting, seems pretty realistic as far as hues compared to most pixel work. Very good otherwise, Such a complex scene definitely takes a good touch with pixel art to pull off. I know large scale is when things tend to get crazy.
