Kazan, I just have two suggestions for you to keep in mind as you make your map.
1) Make sure that some jump node lines/paths intersect like they do in the original FS2 map. That way, the map looks more "authentic." Ascraeus' map of Shivan space looked odd because none of his jump node paths in Shivan space ever intersected (not even once!), while the GTVA space jump paths did intersect with each other regularly.
2) Avoid right angles whenever possible. This is so the jump lines will look "natural." Right angles don't occur often in nature, and we all know that jump nodes are natural phenomena. Too many right angles on your map will make it look artificial.
Aside from that, I think your map is looking good.
