Create an image of a stunning, high quality, and epic fantasy landscape encased within a glass sphere. The scene should be atmospheric and dramatically lit, reminiscent of the level of quality found in a live-action shot on a 35mm film. To recreate the feel of classic cinema, include the grain and vignettes typically associated with films. Additionally, incorporate post-processing and color grading effects that, while subtle, dramatically enhance the visual appeal of the image to a level of a cinematic masterpiece.
