So it takes five/six hours to make one pig mouth look complete. In the meantime, it's Saturday. I'm in a deserted multi-story building on a deserted university campus, and it's about 40 degrees outside. The custodians turned the heat off at 5:00. You try drawing for hours when your fingers are frozen. Another problem with this lab is that I don't have a key and the door locks behind you. Therefore, no bathroom breaks and no food breaks. The cafeterias close at 6:00 (that's a commuter school for you). So I'm freezing, starving, and oh yeah, the light bulbs blew out on me, thus leaving me trying to draw in the dark.
But it was soo worth it to get the damn pig over with. Pig teeth are complicated little buggers. They have the most compact teeth-- basically they have what looks like three or four piled on top of each other. It took me twice as long to draw the pig as the cow, and the cow is a lot bigger (I'm drawing them to scale).
