Results Comparison

The following grids of images have been generated using:

the same public generator (modelId: WMFVfL6ASISizG1T7X2NNw aka "JRPG Adventure")
the same seed
the same prompt: "a bear alone in dark woods"

You'll notice than the highest number of steps or guidance don't necessarily give the best results.
