If I wanted to be nitpicky, I suppose I could, but all the images are wall worthy to me. Great lighting, beautiful couple, nice mixture of poses and clothing.
No over the top flare, no super saturation, no eye stabbing sharpening, and good composition, very well done. The subjects are very well represented, and not the photographers art..just what one would want for their engagement photos.
As Ryan said, wall worthy.
#2 is my favorite. He looks most relaxed there. You did a great job with a guy who seems self conscious.
I agree with Big Appa. The work here is about the subject, not about the photographer. Your clients should be tickled pink with your results.
I have a few nits. In a few of the photos, his skin tends to go grey. Look at his face in #6 and #9. There's a great YouTube video showing how to manipulate skin tone. It's about baby portrait skin tone. You could do a mask layer and ad just a smidge of correction
I love the dappled light in the background, it there are a few hot spots that draw my eye away from the subject. For example, there's a clump of vegetation on the right edge of #2 that you might consider toning down.
Fantastic set. In the B&W shot, the skin color is quite darker than I would expect, and in #5, the bright road is a bit distracting in the background. Otherwise, they're all great.
Wonderful set. I would hire you if either of my daughters ever got engaged. I am usually able to come up with small, tiny little nitpicks regardless of how wonderful a set so don't take them as too significant. One, I would like to see one shot where she is looking at the camera and he is absorbed in her. Just a classic pose that I like. Two, I love here wine colored dress with his blue jeans in the first few. I wish there was more color contrast in the last few so her white dress (also those with her light blue top) and its fine detail could pop a bit more. The similarity works fine in the last shot as they are on opposite sides of the frame and the lighting on her is fantastic.
