For my dad, who loves pine trees:
It's weird, but I think in nearly every one of my art classes, we have discussed the effect of fear on art within this first week... for example, how being self-conscious or afraid of producing crappy artwork stunts your progress as an artist. Today in character design we talked about how we all have sketchbook "crutches" that we resort to because we know they are safe. Perhaps the thing we draw in order to avoid doing anything we think might fail..
Can you guess what mine is?
