OK, here are my comments... IMHO
#1... is flat. It would benefit from a reflector (maybe gold) or a fill flash. There are no shadows and no depth to the image. I like the pose and the location. I think the angled view could go either way, but the biggest thing is there is no light to make this image pop. The colors have a "feel" I can't put my finger on (maybe because I am not educated enough to know) but they could be more saturated... or you could have been going for that look.
#2... works for me. I like the color treatment, the pose and the lighting. I like the angle, although I think it might work if it were straightened as well. No real complaints though.
#3... The only thing interesting about this image is the angle, and it is not really appropriate. She is almost square to the camera, her head and look are in the same direction, her arms are straight down and nothing on her is bent. There just isn't anything "happening" in this image. The angle isn't needed either. I guess I just don't like this one.
Again, my comments are from a non-professional standpoint, so pay attention to others who happen along. I'm sure they will be able to give reason for some of my dis-likes and maybe even tell you why some of my comments are wrong... or not!
