I noticed in the last picture that there are damage bitmaps in between sections. Do you expect that the station will always be made as if it's a complete ring? When I was planning in case you ever released, I had the idea of having half circle stations, or maybe a few sections connected together. This would be for civilian stations of differing uses, for example, a mining outpost vs. a corporate system headquarters.
By the way, please do finish! Being able to control what a station looks like modularly, like this, can very easily change how flexible we are able to make civilian missions scenarios, not to mention making civilian stations believable. (Mass-produced station sections, custom ordered, are much more believable than giant or even mid-sized fully-made civilian stations.)
