C&C per req:
A nice, albeit not really exciting capture. I would suggest trying to brighten up the blooms a little bit and I would definitely crop the top of the image just above the upper-most group of blooms. Notice the way the stem forms a line which draws the eye away from the lower blooms and out of the image? Leading lines are useful tools, but you want them to lead the eye into the image, not out of it.
Just my $00.02 worth - your mileage may vary.
