Hello I've had my application rejected twice and of course I can't post on their forums...

These photos were rejected for being too similar
Photo 1
Photo 2
Photo 3
I believe the Photo 1 and 2 are miscropped. New photographer over-joyed with getting a good shot. Didn't think about t. lol

These photos were rejected for bad composition/subject matter.
Photo 4
Photo 5
Photo 6
These I don't know. I thought Photo 6 was good though...

I was hoping to get some critiques on these and two more as I feel they might be good enough to be accepted.

Here is a link to my deviantart gallery, which s a better representation than my dropbox one.

Any help/insight would be greatly appreciated!
