Hi Chris,
Too many there to give any really detailed critique, but I do really like no.3 with the beach and birds.
Really interesting transition from left to right with the light birds and watery reflections against the dark background moving into the silhouetted birds and dark shadows against the bright sun - almost a night and day feel going on.
In fact the more I look at this the more I like it and would love to have a look at a larger version (sorry not got time to go searching through the link).
My only niggle is that very dark area at the bottom - not sure it's really adding anything, but would like to see bigger to make my mind up.
Briefly, on some of the others:
Personally, I'm not keen on the processing on no.1, but there's definitely something there with the smile and lovely eye contact.
The camel's another one I feel has potential, but the crop is too tight for me. Do you have any more with all of the camel in and maybe a bit of the background?
