The doors are looking better. I'd reduce the saturation on them a bit as they really stick out at the moment. If you are feeling particularly enthusiastic then they would also benefit from their own drop shadow - probably best done as an all round outer glow rather than placed off to one side if they are to be manipulated independently in a VTT.

You said you were willing to post a xcf? If so, I would quite like to have a fiddle with the water if you were willing. I will obviously entirely understand if you would prefer me to keep my nose out If you do, note that you can't post xcfs directly - they need to be zipped and posted instead.
