Watercolor paintings
Although well represented in the base model and by others's LoRAs, the eldritch vision of watercolor painting brings a stronger emphasis on the tactile sense of a heavyweight, rough paper substrate, and on versatility - this style should apply equally well to a broad range of subject matter.
You don't need particular keywords, but you can refer to 'watercolor painting' - the effect is often of a softer color and stronger paper texture. The model tends to respect 'minimalist' and 'white space' as concepts.
