Robin in the Mud sounds like a reshuffling of the ground state, per your four year over-turn model. Robin in the Snow was a Winterself, for a four year long Overwinter. Now things are falling into a Spring season for you, the Thaw. Messy, no clear delineations, no bold lines, blurry & organic, but warmer. Still a Water season for your Airy temperament, but I think you'd rather be dirty than cold so it should be a good omen.
