Please do post them here, it is annoying for everybody to click back and forth to see them.
Looking good so far though, I really like the use of colours (especially in the STALKER image).
I did notice, though, that the urban landscape image has this strange thing that the foreground buildings are nice and detailed, but the left of the image is left quite scrawly. Consider giving the buildings on the left simple shadows so that they wouldn't look so off.
Unless they aren't buildings afterall and a cluttered beach instead....hmmm.
