I really like the pose and the light. I think that since it is such an edgy background the border works well. Get rid of the weed. Also, I think it is kind of interesting that the outfit and the background seem to be a less than perfect fit...but I don't think it detracts from the photo.
I like the angle for the crop. It certainly gives the image a different feel than if just straight on. I like the colors but they look just slightly over saturated for me.
She obviously has beautiful eyes. I would love to see another shot like this but more of a head shot.
A good photograph. And good processing. I think the lighting and focus is good and I love the colors. There are a few distractions that IMO I would fix.
1. The little weed to the left of skirt as mentioned by yanko.
2. Where the paint has been chipped off the door (normally would be good) but in it's location it is competing with the subject. Example: if I try to look at her face my eyes are drawn to that chipped paint area. My mind thinks it's some kind of writing on the wall and wants to read it. If that makes sense.
3. The first thing I seen was her arm behind her looks like it hurts. You can see her veins and muscle tension as she is putting weight on it. you may try to tone down the area from the elbow to the wrist so it will not be so prominent.
I like the border and your processing work. I think you did an over all good job. Especially with colors and composition.
Nice compositon, pretty girl, I like the green contrasting background. You seem to have lost some of the detail in her hair on the left, and I agree with yanko, the weed's gotta go.
I like the diagonal composition. The colors and grungy background work well. I'd probably clone out that rouge weed or whatever that thing is by her skirt.
