Loki in Prison

I think this time I'll manage to finish all my current WIPs before I start a new drawing! So here is Loki in his Asgardian prison (reading and completely unimpressed by the battle in the dungeon). I wanted to try if it's possible to draw with Copic marker on white gel pen. It works! I had only yellow and red for the force field, but it's also more or less possible to mix marker on white gel pen.
I'm sorry for the bad quality (because I was too lazy to scan this drawing and took a photo under bad light conditions), but I'll replace it when I find some time.

Reference was a screencap of Tom Hiddleston as Loki from the movie Thor The Dark World (2013).
