Think I'm going to leave this alone for a while until the painting tells me the next way to go. Not totally happy with the sky or the moon rise, but it's getting there. Need to do a little more with the water in way of shadowing and work on the splash. I thought about putting in another dolphin; however, with the way the current one is situated, to add another would be too crowded. Perhaps one at a later date.
I do appreciate all the comments and input, it is very helpful.
