Hi, My thoughts on improving yours shots, I'm no expert though. Nos 6&8 are my favourite.
1, Dust spot in sky & horizon centre.
2, Use portrait, don't cut people in half.
3, When composing this shot, I would have stood in front of the crossing to avoid the 2 signs.
4, This shot is split down the middle.
5, Lighten the shadows.
6, Crop the stone pillar, then straighten the buildings.
7, As shot 2.
Happy new year,
Mike (UK), raining again!
