Notable is the twisted thing in the backdrop. That is a roller-coaster. Roller means it rolls, coaster means it coasts. Roller-coaster is quite fascinating, it is a concrete embodiment of calculus. See this geometry reference: Visual Dictionary of Famous Plane Curves
Another notable is the bulbous breasts so rendered by the artist. American loves them big.
