The Lora is trained on MidJourney Images generated with my "Personalised Style" + Monochrome Vintage Art Deco/Sci Fi images.
The dataset is really specific and might not produce perfect results for all prompts.

Works without the trigger words ArsMJStyle, ArtDecoVintageFuture, but gives stronger results with them.

The following tags are not requred , but match well with the trained style and can create stronger "Vintage" effect:
Monochrome, Traditional Media, Sepia, Art Deco

Works great in the 0.3 - 0.8 range, depending on the Lora Stack you use.

Around 1 the Monochrome effect starts kicking in, even without prompting it.

I recommend starting ~1 and adjusting accordingly.
