this is a very interesting shot, but somehow i feel the grain makes it feel weird.
there's just something weird about it. i suspect it's the very very sharp outline of the leaves (or whatever you call that.. ) that make it look weird. it sorta... steals the picture away from the main subject, the "flower" (?).
actually the picture really looks very sharp overall.. and doesn't bring out the "glow" effect that you really want to get... i believe that the glow effect should bring about a certain level of softness.
