The pics would not have the same effect in color - agree on the B&W treatment. tones look good. i'd boost contrast a tad. you may also want to try a set with some grain added for the "film" look.
I couldn't wait to get in here and see this up close! It's beautiful Bruce. I agree that a tad more push on the contrast would really liven it up even more and adding grain or texture might be fun to try as well. As is, it's lovely...especially where the two flower's petals overlap. It looks like they are secretly holding hands and you caught them!
