the model is beautiful, sky light used perfectly. perhaps her hairs are a little bit too much on her face, let us see her eyes and his face. About your photographer technique it's pretty nice. The landscape is flowing so we can focus on the model. you tryed a low angle shot?If u can pm me the result it would be nice. And her dress i do'nt know if a white shirt is the best choose. You did a great job anyway, continu like that!
