The song sounds good to me but I don't think it fits the title, sonically. The piece is a bit more "up-close" sounding. Think "futuristic hacking job." The title of "War Across The Galaxy" to me indicates vast and epic, with lots of physical space everywhere. I'd suggest making some adjustments so the instrumentation sounds bigger. Maybe a little reverb here and there or some other effects. Maybe change the instrument sounds a bit to reflect a larger, more epic sound, such as adding synth pads or changing up the drums. Just a thought.
One other thing: I think the track could use some normalizing or a compressor/limiter or something to increase the volume so the listener doesn't have to raise the volume for this one piece and then lower it to listen to other music.
Seeing as this isn't the final version, I'm curious where you go next. I hope my feedback helps. :)
