This style makes images that look like vibrant wet watercolor paintings with drops of paint running down from the subject.

For some images, I added an extra "drip" or "wet" to bring out even more of the wet dripping look. So something like: dripping wet watercolor drip painting

If you like the watercolor look and don't care about getting the drip look or want to make it more likely for the composition to fill the page, you can take "watercolor drip painting" out of the prompt. It will still make images with drips, but it's less consistent.
