Can't wait to see the Cybershadows Heavy Ordinance Conveyors, however I would recommend two modifications.
Namely I feel that the platform should be slightly lower giving it a more "integrated" look with the tracks. To me it just feels like the 2 connection points on each track are a bit out of place and on a practical level would have difficulty supporting all that weight from the platform/weapon. Unfortunately this may change the way the cockpit sits, meaning that may have to be added to the top side of the platform.
The second thing I want to mention, is that I think the weapon looks fantastic from what I can see, however I feel that a weapon of that caliber likewise needs to be better reinforced to absorb all the recoil. Again, something that is a bit more integrated while still allowing the different weapon options.
Combining these two things would greatly decrease the center of gravity, increase the recoil absorption, and overall give it a far more "real-life" feel (And no I haven't forgotten this is all strictly science fiction, lol).
I understand if that wasn't the direction you were trying to take, just my two cents.

p.s. The war stalkers look fantastic! Wouldn't change a thing. Am also looking very forward to the flamerwagons.
