See, I don't like straight lines. Or rather, artificial lines. (I don't like perfect circles, either.) I'm really more an organic lines sort of artist.
Which of course means that I have to force myself to do buildings and machinery occasionally. It's part of 'making myself into a well-rounded artist', which objectively sounds like acadamic bullshit, I know. The problem is that it's sort of true: If you have anything that you categorically shy away from drawing, you'll find yourself increasingly limited in what subjects you're able to draw. Let me put it another way: How many of you, when you draw a person, have them convieniently standing with their hands behind their back or otherwise surreptitiously out of view?
