My favorite character to come from "Guardians of the Galaxy" hands down is Benicio del Toro's The Collector. He is so weird and such a funny way of talking that he sticks in my mind the most. The director James Gunn described him as a "Space Liberace",which I totally prefer over the generically evil version from the comics.
The Collector's costume was hard to draw since there aren't many good online references of him. I actually had to figure his costume design off of a LEGO figure.
He is done with g2 gel pen, .03 mm tip art pen, .01 mm art pen, and black Sharpie. Of this picture, I loved drawing the face and hair the most.
