hands

It has too much red/blue; kind of sickly purple. The composition is kind of weird. The cement to the left is distracting. It lacks balance. All the dark colors are towards the bottom with the exception of her bracelets.
Though, I find the part where his shirt goes from 2 pieces into one where their hands meet to be quite interesting.

I would crop it in and definitely color adjust. Maybe try shooting again. Definitely several from several angles. Try something more unique. This is done so many times and this doesn't really stand out for me.

Pokie is absolutely right. I feel like there is a lot of wasted potential in this work. Amazing concept, poorly executed.
