Mecha vs Prisoner Spheres

This is a very very late birthday present for a friend (was January 13th... damn I suck, sorry!).
Anyways... kind of complicated to explain this piece, my friend is a fan of the old TV show "The Prisoner", I'm guessing most people here have never even heard about it, but anyways, there are these giant bubbles like thingies in it (except they don't have the triple lenses like on my drawing, hehe). The text says "Yay! Finally out of your bubble!" cause my friend had to spend some time in a sterile room (which we call "bubble" here) cause of some evile sickness and all.
But yay, now she's recovered and has regained her freedom, congrats! =D
