I like the concept and composition. There's something about the skin tones though. Maybe a bit too red? Sorry, I'm not very good at technical critiques.
the bottom left corner is reflecting quite a bit of light back at the viewer...to the point that the woman's nail tips start to blend into the background. this makes for an awkward viewing of this image. i would be interested in seeing how this image would look with more diffused lighting, and warmer light as well.
Why is the ring in thw rong finger on your husband? Lovely shot. I hope this was in BW with the contrast boosted as well as the levels. This would have been more powerful. 6
