I want to see th last one finished. Now!
Is it going to be a dome with a city inside of it? Or an artificial habitat? Or a gigantic planet rising over the horizon?
It's a good start, in any case; keep addin' them layers.
Oh, and perhaps the brushes on the moon/dome could enhance their spherical natures even more; there are a couple strokes that are flattening them out a bit.
Oh yeah, and thanks for pointing out that type-o in my comic
