Haha, you taught me this style Ben, trust you to have a head with the same brush set :P
I used maybe 2-3 brushes per head, but they were edited for flow and fit. Head 2 looked like a dragon, face wise, but I was struggling to keep the flow to the back, so after doing the face shape, I worked from the back of the head to the front. Big mistake, but as these aren't for a set or anything, I decided not to bother editing, I'd rather just make a new head :P
Colours were just slapped about, randomly picked, as again, these aren't designed for use, only warming up my skills again, these are the first two heads in 2 years or so, i was highly impressed with myself :P
Definitely a few parts needing a trim, most obvious one I spotted being on the second head, in the middle below the face.
tl;dr I suck, couldn't be bothered to fix, shall make more.
Could anyone describe how to use polar coordinates to me please?
