nice, but the tree shadow needs more lens-type blur, and the current Gaussian-blurred lit spots on places like her left breast are jarring.
(A Gaussian blur of a bright point yields a soft-edged puff, while dappled sunlight that is filtering down through leaf gaps is distributed in more evenly filled cicles, without much edge feathering, because what you're seeing are in essence many pinhole camera images of the solar disc. Of course uneven gaps dont produce perfect circles, but hopefully you get the idea-- the point is that for realistic looking direct sunlight shadows, artists should rely more on lens blur filters, not Gaussian or iterative blur filters)
