>>8041648OP here. I uninstalled SD because of some personal reasons (hardware and actually lack of personal interest), but the prompts I used were:
(masterpiece, highest quality, 16k, high quality, best quality:1.3, highres, digital painting \(artwork\), detailed background,amazing background)
followed by the proper desired theme (forest, snow, beach, etc).
The negative prompts were:
(worst quality:2),(low quality:2),(normal quality:2),lowres,((monochrome)),((grayscale)),watermark, blurred, bad face, old, ugly, bad anatomy,(long body :1.3),(mutation, poorly drawn :1.2),(extra fingers:1.2), ( extra fingers, deformed hands), (poor quality, bad quality:1.35), boring_e621_fluffyrock_v4, boring_e621_v4, negative_hand-neg, EasyNegativeV2, badyiffymix35, fluffynegative, updn, an11, SimpleNegativeV2
I would add humans, people, cottages and other keywords to the negative ones.
Most of the negative prompts were there because I had set them as default after following a random guide I found while setting up SD. I hope that helps, anon.
And finally the dataset used is called "Ghibli Style Mix - v1.0", it's on civitai.
