Holadem: I just stumbled on this thread.
I agree with everything Scott said. I like #3 best. Verrrrrry nice. Colors, background contrast, subject, even the poster all work together to make it an excellent photo. And, on #1, the people and buildings are incredibly fascinating. That's why I agree with Scott about going landscape vs. portrait. While the effect of the sky glow is cool, its the nature of the market that's intriguing me. Less sky would have allowed you to open up the iris just a bit and capture more detail. Just scrolling the picture up the screen of my monitor and using the top of my screen to "crop" the photo just above the church steeple shows how the sky, steeple and palm still impact the photo in a nice way leaving you more room for the foreground.
But hindsight is 20-20. Those are three nice photos. (Come to think of it...I guess #2 really is "hind sight"!

)
