American Locomotive Company 4000-class 4-8-8-4 articulated, coal-fired, steam locomotive. Also known as 'Big Boy'. Jesus. Should I even do this?! It's overwhelming to say the least. I originally wanted this to be a Rhino 5 learning experience, but it's a massive horrible beast and I think I shouldn't bite off more than I can chew so early in Rhino. But even in ZBrush... I don't know. Am I a fool for taking this on?
