Abstract Thursday: Tree Shapes

This week's challenge for Abstract Thursday is shapes, so here is my offering.
I always like the shapes of silhouetted trees, and there are plenty of bare trees around at this time of the year which stand out nicely against a blue sky.
I went out and snapped a few this afternoon, then wasted spent an hour or so playing around with Photoshop. I quite like the effect of trees floating in the sky. It's far from perfect, but I have spent enough time already on it!
Thanks as usual go to Ingeborg for hosting the challenge.
