Excellent MOC. There is an extra-special impressiveness in the fact that you could choose between The Princess Bride or the forced perspective categories, and both would most likely be formidable entries. Love this movie, love this scene, and your portrayal left nothing to be desired. Nice work.
The scale of this is brilliant and forced perspective looks great. Do you think you can squeeze in a bird of some sort circling below the climber to add to the suspence??? Just a thought, but it looks insane as Is. Nice work! :D
