Denise, I really like the subtle framing of the BG and left sdie greenery, and your good focus on the left flower center. Nice comp with the placement, and I agree with Jackie about a little cropping.
Beautiful cosmos, Denise! Great job on saturation...magentas can be a real bear to get right and these look really nice.
Other than a small crop as the others suggested, you also might want to look at blending the right side a bit so the divide between the ground and the greenery is a little more subtle and less of a hard edge. I know it's blurred but a bit of cloning the one to the other might make it even more gradual so your eye stays on those beautiful flowers.
