Well, where do I begin?
Playing with clusters is a fun game in where nothing ever seems to go wrong, at least for me. It is similar to painting, only exchanging brush strokes for clusters, and some of the results can be beautiful even without single pixel AA here and there.
Hopefully the image will speak for itself, im burned out over here and too sleepy to type lengthy. But I'll come back to this piece and comment more soon. I might do the hands next time.
