What a charming young lady! Sweet picture!
The highlights outlining the hair are nice & really set her off from foreground/background.
Personally, I would have enjoyed seeing a second back-light set lower to highlight more of the strands of hair. However, her hair appears to be thick, so I'm not sure how translucent it would be at any angle.
Over-all...Great entry!
This is a good use of backlighting - just a touch too "hard", though - makes the highlighted hair look a little too thick. But I do like the approach, and it's a nice portrait!
she's a pretty girl, but not sure if she looks that comfortable in this pose...I actually think the backlight spoils this shot ans her hair is a little messy in the backlight area
