Made a speed drawing of Loki from "Thor" and "The Avengers". That you can check out here: [link]
The total time was three hours, but spread over three days and therefore the different lights.

I have used:
- A3-paper
- Pencils: 2H, HB, B, 2B, 4B and 6B
- Charcoal
- Graphitone (pen)
- Tortillion
- Kneaded eraser
