Photo 1: Not nuts about the composition, seems weighted at the bottom of the photo, but is very nice
Photo 2, Awesome composition, seems to need a slight levels adjustment, lightening the midtones just a bit, not much, just a tad.
Photo 3: Great composition, good exposure, needs just a little more contrast, the petals seem to run together.
