Here are two absolutely gorgeous Filmation layout illustrations of He-Man from the He-Man and the Masters of the Universe episode "The Dragon Invasion". In this scene He-Man is shielding his eyes from the near-blinding glow of Skeletor's transformation into a giant! Interestingly, in the layout artwork, we see that the artist requests that shadows be placed on top of the cel in order to make the sequence more striking. However, in the final episode no shadows were used.
