Nice! lots of good movement. I have a Little Leaf Linden I should do this with. What's the species?
I went on a critique of trees once with Boon (at a PSBA conference in Olympia) where he criticized a windswept DECIDUOUS. He said that because deciduous lose their leaves in the winter when the winds start blowing, you would really only see a coniferous tree as a windblown in nature. But perhaps you would see a "wind blown" which is a tree in the moment of the wind blowing through it's leaves.
Still, I think windswept is a great form for any tree.
