Spike headshots speed paint

I've been working to wrap up Dr. Who 9 today (which will be done tomorrow night) and I was getting burnt out. Lately I've noticed that I can frequently recharge my batteries by doing a quick speed paint on something else. Coincidentally, I saw 's inks over ChrisCross's Spike headshots and I thought it would serve the purpose of a speed paint. So I did it and I had a blast.

BTW, if you were wondering, the splotches of colors behind the heads were just there so I could grab the environment color and the secondary light source color.
