Oooh I love number three! I wish that we could see more of the diamond but the color tones and espcially the textures are beautiful. 5 is awesome, love both the idea of the sihlouette and the symmetry of the location. 4 I think is an interesting concept but I think it could have been improved by being shot vertical. Isolating on just the two of them at the different depths could have been really cool imho.
And Asbury Park is an awesome place for an engagement shoot, I've always wanted to do one there... Asbury holds a special place in my heart, we have two shots of The Palace / Tilly being torn down on our wall, one of my early shots after buying a brand new 10D awhile back... ;-)
