wshi, just my opinion
1. would have been better if you were standing where the ladies are, cutting them and the building to the right, out of the shot. Both are distracting to me
2. I like it, the bloke is clearly enjoying the sunshine and seems happy, and the background is also fine IMO
3. I am trying to find what your main focus actually was, the building, the girl?, but as composed, I do not think i see what you want me to see
4. Almost the same as 3, it is just to "busy", leaving me not knowing where to look and what to see. I think if the bloke on the bicycle was not in the shot, it would have been nice
5. Nice clear and sharp close up of ?....showing you've got a nice lens there
6. I like the most, if only, The silver flask? and red sellotape holder, was cropped out, and you took it from a lower angle, to have her eyes and nose clear in one of the grid spaces
Thanks for asking us to look at it, it also help me to learn to cocentrate more on composition when I take a shot next time
