nice shot... i think i would have pulled back a little bit more so you could see more of the top & side that got chopped off a bit... it's B&W, but i wonder if the pic wouldn't be more interesting with some color?
Interesting subject! I think the advice given so far is right on. Try a reshoot and get the entire bouquet in the shot (or make an extreme crop and focus on just one or two flowers) and increase the contrast.
