Ring stations always look good as jumpgates. 8)I like the style of my old ones, which are modified versions of your first green station, better but these here a bigger.
By the way, do you intend to give your new sprites faction numbers like your previous ones? That makes organizing them (on OGA) easier. It's always good to have nice packs. :) I would just continue with the numbers from the previous sprites.
Possibly with the next 2, but if I do any more after that it will probably be 1 at a time.
