Fluorescent Monkey, process view

Here is a process shot on the creation of Fluorescent Monkey, as requested! Before this, I sketched on paper, with brushes and then with pencils, many times.
I used a golden or Fibonacci rectangle on the tail of the y. The individual curves on each letter were created with concentric circles, as seen on my other shot, Logo Circles, at https://dribbble.com/shots/2187060-Fluorescent-Monkey-Logo-Circles .
I would post a shot for the circles applied on every letter, but as there are so many, it would be confusing!
