If I may say so I'm rather pleased with how this is coming out. I might quibble over some very small things, but overall I think it works well enough. The essential concept is the same as I had drawn all those years ago, but this version has detail better thought out than before. I admit it's also nice to see it in 3D.
I'm not sure what else I want to add in detail---I'll give it some thought---but I think I'm ready to think about painting more specific colours.
