This is an AMAZING piece of art...the single heart colored red is eye-catching, standing out from the white background. The focus on the single red heart is also very nice, and the way the background gets blurrier as it goes back is very good. The only thing I'd really change is the heart to the red heard doesn't look white like the other hearts, and personally, I think it would look really good if all the hearts other than the red one looked similar.
The metaphor in this picture is stunning...and I hope more amazing work like this comes out.
