thanks! i'm still not sure how to make it work better as an experiment, because it feels like the subjective and the objective senses of correctness are somewhat at odds...
you have, yes, kind of reached the "end," in my drawn end-state the thicker dull pink lines in your red zone are all along the left and bottom side, vaguely gesturally following as ripples of the brighter pink circles. also aesthetically i would probably not choose to put the blue sparkles touching pink lines like that... but, you have reached what i would consider correct! at this point i am just describing a very loose sense of what i like, haha.
did it seem to you that you wanted to assemble the picture accurately rather than however you like?
