He appears too aggressive and she appears too timid. I think the appeal of this photograph is in those facial expressions. Nicely captured.
Colors could have been boosted a bit to enhances the skin tones and clothing. While I'm not a big fan of oversaturated colors, this one appears a bit flat.
There is just a world of emotion in this. A true candid. Marvelous shape formed in the negative space between foreheads and noses, as if their whole world were there. Lovely how the noses don't-quite-kiss. I wish her ear were sharper, and perhaps a little green cast removed from the image. Wonderful picture.
