I didn't mind the lighting the first one too much myself...nor the fence. I think the photo and your model look great
I don't really know what I feel about number two. It's also highly symmetrical and I'm not sure it works for that (unless that's what you were going for).
3 is good, but this time the background does seem a little distracting/busy to me (especially around the subject's face).
Personally, I enjoyed all of them, even though they are not my style. The first looks like Tim Burtons "alice in wonderland." It's magic hour, the color is warm but her skin tone is blue. Very much like the coloring of that movie.
The girl in the first one has an ethereal quality to her. She looks like she should be in a Renoir painting. The gate doesnt bother me, the framing does a bit and I think you could use a tiny bit of fill on her face to warm it up. Some excellent shots for your first month with it. I would also say try to play with your composition a bit more. You seem to tend centered horizontal shots. Flip that baby vertical too. Gratz on new gear.
she does , she is my little sister, I think that she makes 90% of that photo to be honest, If it was anyone else I doubt it would have the same impact as an image.
I agree about my composition completely, and shall try taking more vertical shots - Thanks a lot for the kind words mate.
