I'll give these a go! First off, seeing as she's your girlfriend and, by the looks of it, enjoys being in front of the camera..take full advantage of this!! Shoot as often as the both of you can stand. You have a very good understanding of what you want in your photos and practice practice practice is going to be your strongest ally here.
To start off you have some superb, well fitting photos and some that don't mix too well. #2, 7, 9 (you figured out shooting up the nose
), and 13 don't seem as up to par with your other photos posted. I'm very glad you went with the 85 for these..that buttery smooth bookeh is very pleasing to look at! The first photo is a natural looking pose (could have seen a little more or her other arm, but i think it's ok) showing both her curves and great shoulder, neck, and chin lines. Such a great spot for this photo; lighting is vivid and even and her eyes are remarkable against this background. You're really setting the bar high with the first photo!
Second photo doesn't mix well for me because it's one of those "trying to be sexy" appeals in a non-sexy area. Don't get me wrong, it can be pulled off in a similar area, but pose doesn't work here for me. 'nuff said.
Third photo i would say shares many of the same qualities as the first photo with difference being her eyes aren't as vivid. A mental note i would make is the open mouth knock em dead type look (not sure how else to describe it) works better with the camera shooting above eye level. It just kind of gives off a (hate to say it) boring feel to the model.
Fourth photo helps to back up my previous point; she has a much better slightly open mouth look when the camera is even/above her eye-line. I dig the processing but we've lost her great shoulder lines from this angle. Something to keep in mind for next time.
Fifth photo has the mouth business going on again and an awkward hand position. Just not on par with your previous shots. Sixth photo is another great shot but i would tone down the highlights on her chest. Once it becomes difficult to differentiate her breast from the clothing, it's usually a good time to bring some of that detail back. Have i mentioned that the composition is spot on with every image so far?? Very well done there.
Seventh photo is somewhat similar to the second one..it just doesn't seem to fit too well with the rest of the set. Eighth photo has a whole lot of good stuff going on with it, but the turned degree of her shoulders throws it off a little. Besides that it's a great shot!
Similar to two and seven, your ninth photo just doesn't fit well with the others from the set. The lighting isn't as good and i'm almost more interested in where or what she's looking at off in the woods. You already know what you did with your tenth image however, keep this shot in mind. Had this been taken up near eye level i think this would have been your best image of the set!
Personally, i don't think there's anything overdone about the upside-down shot in photo number eleven. She has a fantastic gaze into the camera that well captures her, again, very vivid eye color thanks to the great lighting. Pardon me if i go too far into this, but this is just one of those awesome, subliminal battle photos. With portraits, we have a tendency to rest our eyes at the top of the image. Well, we all very well know what our eyes are resting on at the top of this image
but that look, that stare, the expression and those eyes are just pulling the viewer's eyes down into her intense focus. I honestly love everything about this photo and it has set a new bar for my further critiques (!!) and therefore had decided to stop my critique on this photo
Images like this are ones that many others will strive to achieve.
