Photorealistic Pony XL

I am happy enough with the results of this version to call it a release version, though it does have some kinks in it still. I found that reducing the number of source images from about 200 to 50 seems to have massively increased the quality without reducing flexibility any. Since it was only trained at 256X256 it might have some blurryness issues, but using an upscaler should help with that. It also seems to occassionally produce an oil painting style, so I recommend using negatives such as "2d,cgi,source_pony,source_anime,source_cartoon,source_western,source_furry,shiny,plastic,glossy,2d,cgi,traditional media" to prevent it from doing 2d or cgi style art as much. Just the keyword "source_photorealistic" should work in positive prompts, though adding "photrealistic,photo" and similar triggers can also help.
