I really like this piece! I'm a big fan of minimalism and the vast white expanses really add to the overall scene. I think the division is important too. Maybe the white would be too imposing without the separation, though I would be interested to see it. Nice touch on the coloured kite too.
The choice of black and white goes very well with the black background/border and adds a somber/solemn feeling to the piece. Also, having two photos in one picture is unique, and keeps the viewer guessing as to what is really being said between the people in it. Amazing and stunning capture
