[SD2] BerryArtify

This model belongs to the SD2.1 series.

Waifu Diffusion 1.5-based, inherits that license.
The goal is to create a Super-Realism model with smooth and sharp lines, which is based on a finely-tuned model with additional learning.
The backgrounds and compositions, which tend to be omitted comparatively, have also been adjusted to give a wider range.
