I'm finally beginning some serious efforts to break away from the cartoony stuff I normally enjoy doing and pursue things a bit more realistically. I'm starting with strict photo refs at the moment but I'll eventually move on to life drawing. I used the old tried-and-true grid method to maintain proportions while drawing. Hopefully I'll get to the point where I can accurately eyeball everything, but one thing at a time.
These are images pulled from a Google search for faces/portraits/headshots. The last one is me, taken by a coworker.
