Not too bad. One issue wit the horn player; his shirt collar, being one of the brightest spots in the entire photo, is improperly tucked under the collar of his jacket on one side; this is the responsibility of the photographer on every portrait; check collars, buttons, necklaces, neckties, hair, and all clothing on each and every shot. Ladies necklaces are a BIG problem, with clasps often in the wrong spot near the pendant; neckties are often poorly tied by guys who don't wear ties often; collars often get messed up on jackets when a man is not used to wearing a suit; and so on.
THe kid against the wall looks a bit "flat" in terms of contrast, but I like the pose and the general effect. The young soccer player: decent job of using the two stadium lights as plausible "sources" for the dual side-light accents on the face. Again, a bit "flat" in terms of contrast, and it's a shame the top of the head is lopped off. On the other hand, the use of the soccer pitch, and the interesting curved line behind--really nice! My main issue though is that the lighting is not set up fully in accord with reality. THe shadow on the player's face is camera LEFT. The light from the background shows the "wrong side" lighted...the left side of the background is bright, the right side is dark...that's...just...backwards. It makes for a lot of contrast; the camera right shirtsleeve is bright, but it's in front of a dark background; the camera left shirtsleeve is dark, but seen against the LIGHT side of the soccer field...
20,25,30 years ago if we saw an image like this, we'd flip out and INSTANTLY likely have a negative reaction to it, but today, with more and more amateurs shooting on-site flash work, and with the rise on "dual-sun" images from professionals, these look a bit less like mistakes than they used to, and many people without finely honed visual sophistication will overlook this kind of result.
