I have been tinkering with this model enough so I figure I might as well get some form of it out there, while I tweak the specifics.
This model is intended to sharpen, enhance, and add background detail. This model was trained on very hi res and detailed images from e621. So hopefully you can use this model to add a little pizzazz to your images!
Thru my rigorous testing I have noted that this model will help backgrounds make more sense, and will create a better relation between furry characters and the surrounding space of your scenes. Give it a try and let me know!
