This one's not too bad. It's a good 'candid portrait' of a camera, which is not a type of photo that I see many of at all. That makes it more interesting than it would otherwise be, so, good job there. Execution is good too - clean and straightforward, with the visual emphasis where it belongs.

A technically good and moderately interesting snap, but I'll use it to make a point: at events like this, with lots of people and thus lots of potential photographs all over the place, making the big papier-mâché sculpture or other stand-out objects the focus of your photos is a mistake. This isn't to say you can't take pictures of them, because that's stupid, but you'll get the best results when you think of them as props rather than subjects. Look for people reacting to them, playing around them, unconsciously imitating them, etc., and you are apt to find more significant photographs that way. (You will of course want to include the stand-out object in the shot for context; just make sure you emphasize that it is a supporting element in the shot.)

This one might have had potential, but the clutter in the background interferes in a fatal way. The woman's head is lost in a sea of identically-lit and equally-in-focus heads, and as a result it's hard to even tell what the subject
is at first. If you weren't able to find an angle that minimized background clutter, you should have tried the widest available aperture to unfocus it into irrelevance.

This one is technically good as far as clearly presenting a subject is concerned. I don't think you managed to make it compelling (exaggerating its size and the bulkiness of the form is one way that comes to mind), but still, it is good and clear.
I don't have much to say about the rest; they're pretty ordinary.
