Not sure if my opinion matters (since I am not an artist on par with you) : )
Beautiful work, I love how you can add so much emotion to the characters and even the setting. Only problem I had was the bottom part of the dress, but that's really a small detail and I think it's fine to keep it. Basically from below the bodice (left side) to the ends the dress seems to meld into the guy or the background, kind of making her ethereal or see-through as well. Beautifully done though : ) I love this piece and keep up the awesome work!
For some reason the movie "Ghost" popped into mind although the style in this one is nowhere near it. For your benefit.. Instead of stranger, I associated him stereotypically as her dead lover. I cannot help admiring the stitching on the helm of her dress and very stylish figure on the floor. I'm also glad to see you are not afraid to use color.
