For the most part I'd say pretty good photos, my only few critiques would be
1. Photos 2-5 weren't the best color wise, they seemed to have too much of one color, like mostly all orange or all blue (like 2 especially it felt flat and lacked color depth). but photos like 6 were great balance wise.
2. Maybe work on your composition, if you want things to be dead center, make sure that they absolutely are. If not it detracts from the point of the photo and makes the viewer focus on the fact that the photo is just slightly off. But some in there were well composed, like the paper airplane one (maybe my favorite photo of your lot.)
3. Whenever possible, underexpose. There were a few shots that had some really white spots in the shot, and they made it seem really bright and washed out. Not too bad, but could be better. My advice would be to shoot RAW and set your EV value down at anywhere from -1/2 to even -1.5 or -2 depending on what part of the shot you're metering for. The reason being that once you overexpose the shot, you can't pull down those highlights even in post. What has been overexposed cannot be undone. If you underexpose certain parts of your image you can pull those shadows out in post with very little issues.
That's just my opinion, and I thought they were pretty good photos (way better than average) so don't take my critiques away as that I didn't like the photos altogether, just what could take them from good to great. +k man
