To expand on George's question, did you move the focus point manually and refocus the lens using autofocus, used manual focus to refocus, locked focus and moved the camera using a focus rail or used some other way of taking successive shots?
The green leaf on the top is rather shiny and sharp and attracts a lot attention. I would try to pp it to make it look more like the two leaves at the bottom and also brighten up the flower a little.
