Ahh that's actually really good advice! I knew about looking at people as they moved, but the gesture drawings...nobody's said anything about that! I always thought to look at anatomy (which I know I should) but gesture is actually really helpful as well! Thanks!
Pencil tool works great for cleaning. The faucet option for the erase tool makes it even better, draw a few lines and check that out unless you know about it already.(when using erase tool, look on toolbar for leaky faucet)
Cool,I had not used it before,I set a button on my wacom pen to delete and just select whatever i want to delete with ctrl+shift .It's a bit faster because I can drag-select with ctrl and this way I don't have to switch tools.
