Dipping sea green over sandy's green is one of my favorite combinations. I was expecting more of a pearl-effect like you see in Bowl 56. Maybe the lack of edges for the glaze to catch prevents this from occurring.
I might try to reglaze by dipping rutile over the sea, and then another sea dip over the rutile, fire this in reduciton.
