Let me guess, you've been to Berlin? Great catch-up, a few stand out for me.
Dark - the last few remaining bits of the Wall certainly make an interesting photographic subject. Well composed with strong leading diagonals and a very dramatic sky.
Architecture - the little people in front of the MP's offices (?) give a great sense of scale. Well composed, the eye of the viewer is drawn into the circle in the middle, and great light. Shame about cutting off the roof on the right...
Minimalist - Great light, the photo has an almost abstract feel to it, and it's very minimalist.
