Thank you, Alan, for giving me the opportunity to see my image through your eyes.
Just as I know it would be, constructive criticism is always extremely useful.
I fully agree with you, the image is on the dark side. The light is only from the right side here, so it is also quite directional, leaving the neck area in quite a deep shadow.
Regarding the blue, yes saturation is increased, but not as much as may think. I'm not an expert, but I believe this is a male and those that I have seen, have much more blue in the eyes than the females. The image being dark does have a tendency to saturate colors further.
I'm going to attempt a repost. Here I brightened the image, but not quite as much as in Alan's proposal. I also removed the saturation that was added in post processing, so Larry can see how the original blue looks like(although without using a color checker card or similar at shooting time i fear it is impossible to get it 100%).
Also I had a study of Alan's version and i thought it looked much more sharpened than mine, so I thought I had been a bit too conservative, so I also added a little more sharpening.
