I drew this at college at 12 am in the morning. It didn't take too long to complete. Mewtwo has been one of my favorites for years, so it was a treat to know that I could draw him without a reference picture. (I drew him that much in middle school...^^
How did you learn to draw like that
...if that's okay of course XD
Still, its excellent.
Oh and Mewtwo does have a mouth.
