This design intrigued me, so I decided to try my hand at it. Bear with me, I just got a new scanner so I'm still trying to figure out decent settings for it.

A couple things:
I envision this as a high speed, medium range space use mech, hence all the thrusters.
I tried adding missile racks to the shoulder boosters, but it just didn't look right so I left them off. They could always be optional.
I didn't know if Aegis Overlord had a decided-upon logo, so I just did that AEO logo on the side.
The guns just seemed like they would be a better fit as rapid-fire weapons, hence the ammo belts (plus I personally just prefer rapid fire guns).
As for melee, there's room in the forearms for some sort of deployable blades or maybe the hands could charge with energy or something along those lines.
I didn't know whether the cockpit was in the head or torso, but I was kind of thinking the pilot could climb in the back part of the head, sitting in that second part between the head and the main back booster.
It's a space mech, so it needed the fuel pods.
Anyway, let me know what you think.
