His face is dark and maybe not in focus. I like the composition and the trash in the corner of the photo. The look on his face really makes me wonder what he is looking at.
I gave this image a 5 in voting. Its great for a candid - I love the expression and emotion in the image. Unfortunately, the focus is slightly beyond him and he is slightly blurry. Also, the contrast is weak. The brightest spot in the image is the white bag in the background which draws my attention.
This is a nice capture of the person's joy, however their head blends into the person standing next to him. Improvement would be achieved if there was separation between the main subject and the background.
Image is a little bit too dark to make the man out clearly - this probably would've been a bit better if there wasn't a person directly behind his head - the black skirt creates a low-contrast buffer around his face so his expression doesn't stand out as much as it should.
