Offline Perspective Attempts

Was away from the computer most of the day but thought id just do some practice on the drawing pad I had handy. I'm mostly experimenting on making looks from different angles , and trying to figure out where the chin , nose, mouth, eyes should be without worrying too much how to draw each of those so far. I seem to have a BIG problem with where the chin should be. I'm working on it though. I'm trying to adapt the Loomis Method to draw the heads, partially because it seems sensible to me, partly because its easy to visualize, and lastly because it reminds me of Dr. Loomis from Halloween ;)
