It's Mr Mistoffelees from Cats! The magical Mr Mistoffelees!
I drew him only a few months after my 14th birthday - after my obsession with Cats the musical started. I had never drawn portraits before, so I taught myself how to do it. You know when you're obsessed with something, anything is possible... I also learned the songs and the choreographies in a few weeks.
The scanner kinda destroyed him...

(Also I'm not a native speaker and I'm sorry if I made any mistakes)
