Pretty competent location OCF work Jake. I looked at some of the Original-sized shots on Flickr. Whatever lens that is has a slight bit of purple CA showing up on some frames. Not visible except at the big sizes though. What were you using as a light source?
Agree ^^ I'll also add that #2 is one of the very few successful "shooting from below" images I've seen here in a long time.
You know, I look at each of these and I wonder if she might photograph better when there isn't open sky.
While she is slightly dark complected, her skin also must be quick reflective and thus in every shot her face seems quite contrasty - perhaps reflecting the brightness of the sky.
She has a charming natural look and, if she is a willing subject, it might be a great learning experience for both of us.
