Really nice to see your process up with that last one. You seem to be taking this advice of anatomy to heart, and that's awesome. Just keep at it, and hold yourself to a high standard. Also traditional to digital transition is incredibly painful for some, but inexplicably easier for others. I've been at it with my pen tablet for a few months now and I'm still not satisfied.
On an unrelated note I like your avatar Unmei, I'm a sucker for samurai/rounin XD
