Open Shade - Outdoor Portrait

I'm half way through my photography course and am now working on the portraiture part including but not limited to studio lighting, location (studio and outdoor), child & pet photography and wedding photography.

This is my outdoor; open shade portrait. This was taken outside, under a tree in the shade, no flash, no extra lighting of any kind (except for the little sun shining that day) I used a tripod of course or would have never been able to have gotten it sharp and clean.

This is my daughter....she'll be 17 in April. I usually don't put much out about my kids online for their safety but she's just so beautiful I couldn't NOT share!
