*EDIT* It's not much, but I darkened the mid ground a little. Until I learn more efficient techniques for digital work, that's about what I can do.
Background could have been better, but overall I'm pretty happy with it.
This is a pic of a battlefield that has been "broken" (i.e. battle lines have blurred into one big mess.) Faction units (in green) fighting Federation units (in desert paint.) In the background you see some Federation missileers and in the far back, one of the main assault platforms and its compliment of mecha.
The title comes from "ace" pilots -those who have earned a name on the battlefield. Hiro groups aces into two categories: "runners" and "shooters." Runners employ exceptional maneuverability, and often specialize in melee tactics, while shooters are highly flexible and accurate with firearms. Typically each ace has a little of each in them. Hiro is THE ace of the Federation. Kana is a runner ace, and Eric is a shooter ace. None of them appear in this picture though.
Oh and something I never mentioned -The Federation refers to the Faction as simply that, or the full name, the "Red Seal Faction." The Faction military and the citizens in Faction-controlled territories refer to themselves as the "Red Seal Republic." Just in case anyone wondered what "RSR" meant on the mech in the foreground.
Also, I realized earlier that I gave an overestimation of size for the mecha in "Dream" -based on my original mechanical designs and the fact that I actually did some approximate measuring, the mechs are around 28 meters tall, not 40.
