Initial impression: Good shot and creatively fitting title. The color of the sky to the left is very nice and the subject is certainly beautiful.
As was mentioned below, the sky on the right side of the image is blown out which causes a bit of a distraction. It's a shame mother nature didn't work with you here and give you the same sky overall. This would've helped to make it fron page material. Also, while the 1/80 shutter speed gives her a sense of movement it also caused a bit of overall blur which also might have hindered you from a better score (not to say 6.03 is bad but you know what I mean). I think her being totally frozen in mid air would've worked out better rather than showing movement.
Overall a lovely image and great idea that you should be proud of.
Thanks for the opportunity to critique your photo Lawrence.
Not bad at all... good idea for the title, and great execution. However I find the space to the left of the model a bit distracting and would crop it out.
I'll give you the stretch on the title. I like the clouds on the left but think it is too washed out on the right sky. I would like ti more if her left foot was not blurry. To really go on the mary poppins bit some sidewalk chalk would have been nice too.
