Primal Sketch

I haven't uploaded in ages! Here's a 5-minute sketch I did on some scratch paper, based on this show I've been watching, "Primal". All I had was a sharpie, so no erasing (which is problematic for me).
I've just been busy lately, but I can't wait to get back to drawing everyday! Also my e-pen died so I am looking at getting an improved one.
