Good attempts I recon. I really like 1 but I'd desaturate the green thing by her head, its really bugging me in an otherwise good photo though you've blown out the sky too.
I'd also crop a bit off the tree in the 4th pic. It takes up a wee bit too much of the frame imo and I think she could have used a touch more light on her right to make her eyes look a bit more even.
2 and three I think your pose is off, they look strained to me for some reason.
I cringe every time another member attempts to edit an OP's image. Good Lord, they are horrible (the attempts at editing, not the OP's pictures).
