Really nice work on this one. HUGE MEGA MAN fan myself. I know hat you mean by it becoming an addiction I haven't even finished my first one and I'm thinking about tons of other one I want to make already lol. Keep up the awesome work man.
i made the mega buster by covering the munny's original hand in sculpey. for the small "barrel" of the cannon, i used a small nut as a base and covered it with the clay.
Did you make the arm cannon or is that something you bought? Also what kind of paints did you use? One of the coolest Mega Man pieces I've seen in a long time.
