Kind of cliche, but I think generally very nice regardless. (its hard to be original in a world with a couple trillion people)
The second shot is tough just because some of the color of the chairs is there, but not all... but really minor.
Something in the third didn't seem quite right to me... I guess maybe because the sun looked like more of an overexposure than a sun... I almost wonder if it wouldn't be better to crop that one down to just the people, or take more of the washed out sun out at least. Might be interesting to try. Still, minor overall I think.
I like the first shot the best... really cool sun effect you have going, sharp silhouette, awsome reflection, and nice colors throughout. To me, this one was totally dead-on.
Cool series.
