I really like the girl in the second last photo. Wouldn't really change a thing except it looks a bit saturated.
The one with the kid with the baseball cap on, isn't too bad, but needs to be opened up a bit. The crop is too tight.
The others are so so, a little washed out and look like you've taken sneaky photos of people standing around doing nothing, which can be great if the people are captivating or interesting, however these people (to me) are not. You're subjects are centred and looking away from you, not in an introspective or podering way, but like they are engaged with something other than you, which kinda makes the photos less interesting.
The shots aren't really dramatic, but I do like that second last one. She is beautiful.
maybe try and put the people on the far right side of the shot and leave the rest free. . you would be surprised, somtimes i think it looks better (my friend introduced me to it, i call it the graeme technique) like these...
but then i again im kinda new to this whole photo bus so im probly wrong
