I love MagnaLuna's art style, but I wasn't very satisfied with the other PDXL Lora available on this site, so I decided to make my own. From my testing this should capture the style better while also having a more diverse range of generations - and being less biased to certain characters.
Base trigger word is "magnaluna"
"pony" - Regular ponies
"anthro pony" - They have hands
"furry" - Everything else
Use "luna" and "celestia" by themselves without princess for MagnaLuna style bias, include princess to decrease bias
This Lora also (somewhat) understands different Luna versions;
luna + white hair
luna + purple hair
luna + dark purple hair
luna + blue hair
I recommend a lower strength for vague or less specific prompts, otherwise 0.8-1 is good.
