I did the sketch around 2005 by using pencil, pen and marker only. The original art is in pretty bad condition with many liquid paper around cleaning up the details. I was so bored in the class so i took a small piece of paper and did this.

Eventually around 2012, while at office and I was again bored coz I had done all my works for the week. I finally digitally clean it up. Maybe I should post the comparing.
