If you lower the altitude level under the cloudscape settings you will eliminate that black area and it will look more like a real sunset. You're off to a good start though.

A very good start! :)

I agree, this is a good start. The pink and blue colors are gorgeous and look well against the black. I like the pale pink water with the reflections of the sky in it. Maybe you can tell, but pink is a favorite color of mine :) The title is perfect and thanks for sharing this pretty scene :*))
