robots speed drawing

This is a speed drawing of the very brilliant idw graphic novel "Zombies versus Robots", by the amazing artist Ashley Wood.
I love the robots in it and just wanted to doodle some out.

I used a fine black pen, black marker, and a white marker (the white is brilliant, i first go with the black marker then cover it over with the white...it really is effective)
