I never actually comment this map because I wanted to see his evolution before I posted my ideas/comments.
I think this map is a mess, it's to crowded.
When I look at it I don't get the feeling 'Wow, this is outer space and it looks awesome'.
1)I think the arrows don't belong in this map, try something else...(laser beam?

)
2)The names are porely placed, I don't know how it can look better...maybe don't make the names just white...add some effects to it?
3)the ness bombard spots are to big and they aren't centered, the cross isn't in the middle of the circle. They are to bright, make them a little transparent maybe...
4) The name of your map isn't readable on my screen, the map is to dark and now it sais 'Aceness'
5) I don't get the light in the map...the bright flash in the middele is a sun?
because the light on Praetos is to straight if the light comes from the middle...It had to be more to the south, same goes for Halo.
