I really enjoyed drawing this one and since it has hands and teeth, I'm quite pleased with the outcome
Anyway, everyone will have seen this ref pic before so I wont link it, I found it on a google search.
It took me around 5-6 hours and is a little smaller than A4.
Materials were: graphite (mech and wooden), carbon, tissue, erasers, cotton buds.
A little note: I'm photographing my drawings at the moment and they are more detailed in real life. As soon as I have access to a scanner, I will upload them all with better shots.
