Inktober- Day 14- Marvin the Parnoid Android

After one of my mates mentioned that the actor that played Marvin in the original Hitchhiker's Guide to the Galxy had passed away recently, I had to give drawing Marvin a go. I messed up the arms a bit, but I'm glad I got the detail on his torso well enough.
Below is just a rough sketch, with some ink marks to work out what nib to use on the final piece.
