Looking back at my stuff I concluded that I really have issues with faces consistently. I'm not happy with how I do them, and often the chosen pose ends up hiding it anyway. Plus at the canvas scale I work I never really spend much time doing any real facial detail so any errors in my approach tend to go un-noticed...

So... practice, y'know. 100% bigger and more face-ier... and while I was at it I figured out a new trick of how to draw fast and loose at large scales which was handy.
