Great macro shot. It was a good choice to not shoot the flower straight on, but to come in from an angle like you did. The shot is also framed well and keeping the inner parts of the flower off to the right rather than centered makes for a better overall photo.
If I was to say anything, it would be due to my being an anal jerk it seems the top part of the stamen is a touch out of focus. Not sure if that was intentional or not. However, it doesn't detract from the quality of the image so it is not of any concern.
