The Elamite Sphere model will generate spheres—small spheres, giant spheres, smoking spheres, spheres in explosions, spheres above the cities, spheres with eyes, spheres with mountains inside—and whatever else you might think of (probably).
The strength range should be set between 0.4 and 1.0; however, I encourage you to experiment.
You can manipulate size, colors, special effects (like smoke, explosions, lights, etc.), people (crowds), vehicles, and landscapes.
Basic negative for the Juggernaut model that I used:
photoshop, video game, ugly, tiling, poorly drawn hands, poorly drawn feet, poorly drawn face, out of frame, mutation, mutated, extra limbs, extra legs, extra arms, disfigured, deformed, body out of frame, bad art, bad anatomy, 3d render, double, clones, twins, brothers, same face, repeated person, long neck, make up, ugly, animated, hat, poorly drawn, out of frame, text, watermark, signature, logo, split image, copyright, desaturated
More ideas for prompts in picture descriptions.
Pictures were generated as they are—no cherry-picking.
