I'm going to give this a shot, even though I'm new (so forgive me if I'm wrong on stuff!).
#1. I like it. My favorite of the ones with the greenery background.
#2. Looks a tad washed out to me. I'm sure the old pros will know how to fix it... again, I'm new! Other than that, I like it.
#3. I'm distracted by the houses in the background. I'd crop in more. Or at least be more down on her level to shoot, and use DoF to keep out the distractions.
#4. I definitely like the idea of it, but it made me laugh 'cause the flower looks like a mustache and it reminded me of manaheim.

#5. I don't really have an opinion. Nice. I can tell it was a sunny day!
#6. I like this one! Great focus and DoF.
I would have liked to see the rule of thirds on this one instead of centering her, but I like it anyway!
Ok, I feel really dumb for critiquing someone else since I'm still so new, but I know how much I appreciate everyone's input when I post, so that's my 2 cents. Now the old-timers can come in and tell me what I said wrong.
