Willy in Sweden

Wonderful shots! But just some comments. #2 will work better with a wider lens. #3 needs a more shallow depth of field so that the 3 areas doesn't look so cluttered. #4 can try shooting it from a lower angle from the ground.
 

Ya, I agree that #2 is too tight; shld have used a wider angle (but only got widest 36mm , also walked the furthest I can to snap).
#3: Confirm need shallow depth of field. Wanted to retouch in PS but too much details to extract. The small CCD on S2 IS is not helping either.
#4: Too lazy to walk to the building... hehe.
