Got a set here that I have been putting together off and on last tow months. 40 more images from my scan folder.
There are a lot of drones in this one. Some transformations and bondage in it. They are all simple inks with shading to them. A text doc is attached as well that has a description of the concept for all 40 pieces.
Lots of Drones!

Got a link for Gumroad and one for Pulley.
