1. The sunbeds/table distract me from the nice background, reflection in the pool is quite nice, right hand side of picture is very overexposed. Due to the sun of course, also there's a small bit of lense flare top right.
2. Shame the sky wasn't more like that in #1, the tree behind the pots is distracting, and there is a pot to the left of the frame that's just creeping into the picture, crop it out.
3. Quite nice, think i'd like to see less of the building on the left, and again the right side is suffering from being overexposed.
4. Makes me creek my neck, I don't like it
