Shots 1,3 and 4 are stunners mate!
1) Lovely symmetry and refflection, and the colours are spot on as well. really like it!
3) Exposure for me is spot on. Just enough detail in the buildings and the sky in the upper area of the shot to hold interest, yet still casting a fantastic sillouhett. Excellent composition as well.
4) very middle-earth-y, lots of atmosphere. Love it
2) For me the shot doesnt really hold the eye very well. Can't really put my finger on it, but there is something missing. sorry!
Overall, lovely stuff!
