Lots of, kinda, difficult problems to work out yet. But I'm really really happy about these much over exaggerated features. Notice the over hang arch at the top and the rectangular faces. I waited a long time to understand a way to add these kinds of details, had to use functions for them. And I must thank Mogn for his help. There is also some node structure from Mhaze being used here as well.
Anyway, a long way to go yet. But I just felt proud I figured out how to manipulate a set of blue nodes, somewhat.
