This is a portrait of a beautiful Chinese girl, adjusted in Photoshop (posterize, 5 levels) then transferred to the pumpkin by tracing over the print-out taped to the surface of the pumpkin. The indented lines on the skin of the pumpkin were faint, but legible enough to trace over again directly with the pen.
This is the logo for the Denver Philharmonic Orchestra.
Three seperate Google img searches gave me the hand, face, and hair stencils, while the butterfly came from my own photo.
