I agree, excellent exposure. Composition-wise I'm wishing to see more of the neck...feels like it's cut too short. I still like it though, and I too like the squinted eye :-)
I like this guy's expression. It looks like he's got something on his mind. Pretty light, too. I agree with Axel in that a vertical might work well if you have more neck to include.
Love it, I like the tight feel here, the light is simply wonderull, the exposure is right on and the comp, detail, colors and BG are stunning. Congratualitons Denise.
