Trained with Leco Score v2
Gave ratings to ~1200 images following my personal preferences:
colours: warmer, more muted, more retro
face: sterner, more exalted, more aloof (Mucha face?)
shadows and coloring: less flat color, complex hard and soft shadows, more lighting effects, warmer highlights
composition: not many changes, but the character is more visible from its background (change of color, lighting, saturation around the main character)
Additional notes
if the image is dark, weight is too high or add 'underexposed' in the negative prompt
negative values make the image flatter, colder, less arty, and could be used for candid analog photos, old photos
some images with very complex compositions have been included, sometimes the Lora makes nonsensical (impossible) landscapes
