I used the following prompt on DALL-E to make them: “POV camera angle realistic picture. Foreground: Hand holding knife. Middle ground: Balloon Monster with scary teeth and scary eyes looking at camera. Background: Forest”.
Afterwards I kept running variations until I got something I liked. And for the final touch I erased the balloon monster itself and added this prompt: “Extremely scary and realistic photo of a Balloon shaped horror monster”.
For the wide angle photo, I used the feature on DALL-E which generates visually similar content. For the right side of the wide frame, I used the prompt: “Sunny forest background”. For the left side of the frame I used the prompt: “forest background with goblins hiding behind trees waiting to attack”. But it didn't give me what I wanted. So instead I just prompted: forest background. And then I erased spots on the trees and prompted "goblins hiding behind trees" for the erased spots. It didn't give me what I exactly wanted, but if you look on the left side, it kind of looks like there's goblins hiding.
If anybody wants to see the failed variations, I'll upload them on here as well.
