When I was a wee lad, I remember seeing a similar poster in a college dorm room involving an eagle swooping down on a mouse. Always thought of re-creating this with Darth Vader and Rocket Raccoon, so I finally went and did it.
Rocket's "bird" is Photoshop trickery. I took 2 shots, one with his open palm hand and one with his fist hand. The fist hand worked better, so I clipped out the middle finger from the open palm photo and spliced it (somewhat badly) into this shot.
