Thanks bikemouse, quite a few people have mentioned the rings. In truth there is a transparency map on them but it has fuzzy set instead of blend transparency. With blend trans it was even sharper and I prefered the fuzzy. As for the tentacles, that's a possibilty but there's actually very little movement from the tentacles. They are slowly crreeping out of the water though I suppose I could add a tad bit of foam in the direction of the wavelets.
