4 and 7 are my favs. I am glad you put 4 and 5 in there though as it would have been really difficult to figure out what I was looking at without the other shot!
I'm with the spiffy Beth, also I like the first 2 photos very much. It is the minimalistic element and overall composition of 2 in particular that catches my attention.
But I also like the abstractness of 4 and the distortions. That park seems to be a favourite spot among photographers? Or did you have a secret little TPF meet-up there??? Eh? Eh?
