I like the color and DoF usage but I think they could be cropped much tighter. I find that dark band at the top of each print somewhat annoying because I can't make out what it is, might be or should be...it's just a random dark line that doesn't fit the rest of the scene.
I like #1 and #2 better than three but as I said earlier, there is way too much dead space to suit my tastes. (I am suspecting you were quite a ways from these guys, given the image compression.)
I suspect that, with care, you could manage a little more in the way of brightness here.
Like you, Chris, I would have cropped a bit tighter; although having a plain 'border' of background does seem to be something of the modern style.
