I couldn't find a Christmas elf style LoRA for Pony that suited me for the SFW purpose I wanted it for. So I decided to make my own. Trained here on CivitAI, and with the 'style' option. I also made a 'character' version. I think it produces passable holiday style. Play around with it. Hopefully you like it!
Suggested prompts: xmas_elf, Christmas, holiday
It is Pony-based, so I see differences with "score_9, score_8_up, score_7_up, score_6_up, score_5_up, score_4_up". Personally I liked the best look with just "score_6_up,score_5_up,score_4_up". Go with what suits you.
I did seem to have a lot of closed eye results, I don't know if that was the negative prompt I was using (55% sure) or what. But if you need to, just add (open eyes:1.2) to fix the stoned look.
