Making a tree, part 1

I have started to make the tree that will be growing to the right of the telephone booth. I am making it as a wire armature tree, i.e. making the branches using twisted wires. I am using a wood skewer for the core of the stem, creating a straight and fairly well pruned tree. This since it sits in an urban setting, and not grows freely in the wilderness.

Here is a picture of the progress so far.
