First thing to hit me with the photo's is the overexposed dress. Being new to the game I might be wrong but I would have exposed to keep the dress detail. I like the use of frames for some of the shots. Photo 2, not seeing the bride's face is a no no for me. Photo 5 would be complete for me if the veil had been captured on the way down keeping all of the veil in shot rather than leaving an awkward crop.
Is there a reason he's not smiling in a single shot? Overall they're pretty good but he looks very uncomfortable/awkward. The impression I get from him is "Oh crap, what have I committed to?"
A few small points:
-You shot them on the same side in every image (guy on left, girl on right)
-Except for one, you shot her face with the same angle, from the same side. They are all a partial-profile on the left side of her face.
-Blown out dress
-They don't look very happy
-The one image you attempted to change things up (positioning of the subjects in #1) you can't see either of their faces. It was a good idea, but I don't like the end product with her looking away from you and his face blocked by her head.
Lastly, I am confused as to why they are in wedding attire when it's an engagement shoot?
