1) I cannot draw realistic looking machinery to save my life.
2) I have no real knowledge about how machinery works and thus cannot invent my own designs of machines to save my life.
Obviously, these are serious problems that must be rectified, but I'm not really sure how. Maybe I should go rooting through my old 'How Things Work' books and try to find some bulldozers or something, but even then, I'm not sure how to find any resources on how to design sci-fi weaponry and androids. Oh well. I'll figure something out.
Maybe I should just stare Doug Chiang's art until my eyeballs fall out of my head.
