#2 gets a C+ grade, because of the sharp edged shadow his left shoulder casts on his chin, lower cheek, and neck.
He is over exposed.
IMO that shadow is a glaring error. Without it, the photo gets an A-.
The dutch tilt in #3 doesn't work for me because of the water and shoreline in the scene. However, your advertising helps balance the shot. Some flash would have made the couple 'pop' better (light advances, dark recedes). I give #3 a C.
I also downgrade #1 because of the what looks like unintended camera tilt (left side low) and their dark legs. With the composition, tilt, lighting I give it a B-
