Your greens are pushing or ARE nuclear in all the colored ones. Number 2 especially...
I don't like your B&W conversion on number 3 either... the tone of her face looks kind of... flat. Someone may disagree with me, but something's off about it. I dunno.
Overall for your first shoot, I don't think it's bad.
1 has a nice feel to it, but I don't like that you cut off half her foot in that one.
#2 looks soft to me and the chromatic abberation caused by the strong backlighting (someone with more technical knowledge please confirm or correct that...

) bugs the hell out of me. And as mentioned... the greens are WAY too saturated and... look like they were painted with nuclear waste. :lmao:
Post in number 3 is cute, IMO, but again, the black and white conversion isn't doing it for me.
4 is a cute idea. I'm fighting with myself over whether or not I would have had her looking slightly at the camera, but I don't hate it as is... except for the processing. You've got that over-saturation nuclear thing happening again.
5 would be nice, IMO, except that her face is WAY too dark for that bright spot on her dress/leg. My eye goes there first every single time until my brain reminds it there's a head above that... mid... region.
Remember what I said about your B&W in number 3? I think I feel the same way about it in #6 too. She also look a little uncomfortable to me.
I know I pulled out a lot of negative aspects, but I really *don't* think these are bad for your first time.
Keep shooting, and keep learning!
