Tree shapes

I think I am developing a fascination with tree shapes.  It goes with how the branches head in the air.  It seems to go in various direction.  It can have a nice effect like a sphere or a cone.  Other times, it look more twisted.  It is those who have a twisted branches path that I like the most.  I have taken a lot of those trees.  Here are a few examples:

The first one seems to be a head with the hairs in the wind.  The second photo makes me think of a glass of wine because of the form of the branches.  The final one makes me think of a ballerina stretching.  This is as fun as looking forms in clouds!
