My first attempt cleaning my lines with the pen tool, A bit of a failure, I like parts but it's rather sloppy,Finding it hard to get to grips with it, and from the videos of seen of people using the pen tool really fast.....well mine took 6 hours to do these lines....so I'm not very fast. Never the less I'm going to keep at it till I get it down.

The character belongs to a friend of mine from deviant art and this is my interpretation of that character
