Retrofuturism your generations. CFG 6 works really well, and 7 on most, but this concept was heavily overcooked by SAI for XL (round buttons, or round badges, etc... is part of the base I could not get rid of).

Zestify (my enhancer LyCORIS) this for even more goodness. If you wish to douse the sepia type sepia in the negative prompt (weight it as well if needed). Tested, and trained, on SDXL 1.0, so the sepia is strongest on it. Try it without the activation word as it is different yet again.

ALERT, the file was changed as the previous release some users reported issues with it, and I have spent the last eight days doing the best I can to fix it. This concept was a major chore, as SAI has it so baked in that it fights your training. This is when a nice concept cleaner would come in handy.
