This image has a lot going for it - I'm surprised it didn't finish higher. But as you know, there were a great many excellent entries to compete with.
One of the common weaknesses of many entries is the lack of impact - but your image does not suffer from that. It reaches right out to the viewer and shouts "proportion" quite loudly. I don't necessarily agree with the comment that it "barely" shows proportion as the left eye is about 1.5 times the size of the right eye.
Your presentation is well done - placing the subject on a diagonal line adds some tension.
Techically, the exposure looks to be right on and the "printing" shows good black and white qualities - good clean crisp whites and some black blacks with a nice tonal range between.
I'm a bit confused by the tech data shown on the image - an f-stop of 2.8 and a shutter speed of 1/10th. I would not have thought the focus on the right ear would have remained sharp at 2.8 - given the focus is most likely centered on the eyes. And a shutter speed of 1/10 most lkely required a very still model and a tripod.
The lighting is a bit "troublesome" as well - with two catchlights in the larger eye - but just one in the smaller one.
The only minor improvement I would suggest is the removal of the bright spots just to the right of the eyelid and in the upper right corner of the image.
I like the attempt here and it is out of proportion, but just barely so...I would like it more out of proportion....make a great human abstract that you really don't see a lot of. Good work.
Interesting take on the challenge. Nothing to critize photographically. Perhaps add more background for context, but I think this is pretty good as is.
The composition is ok but I wonder if it would be a more startling image if just the eyes were cropped. I can see how it was problematic to make the decision on just how to present it. Clever idea.
