My pleasure, Don!

Ah, I see - you got the fractally effect by posterising the colours. Gotcha now I must borrow that idea, the effect is really pleasing!

Tutorial writing for your maps? I suggest when you undertake a new project you take lots of screenshots during the process and then stitch them together with a narrative explaining what you are doing at each stage, how you do it and why!

cheers and looking forward to seeing the next iteration.
