Halo fanart, set in a cave, inspired by the show, since it was unfortunately my only exposure to halo's story, as I did not grow up playing video games. Here you'll see Master chief interacting with the relic, Cortana there to monitor him, while one of the ship's is slightly visible in the sky. My process when perspective is involved is, I usually tend to use clip studio for the perspective guidelines using the rule, and then paint in photoshop.
