Many thanks!
Dude, 99% of the work was done by PillowBlaster and DoomNukem. All I did was add hands and change colors. Even if I wanted to, I doubt I'd be able to make a centered version of this anytime soon. These simple edits are currently the acme of my digital art skills (I say "simple", though it sure as hell didn't
feel simple XD).
Also, not a big fan of centered weapons. Angled weapons are where it's at for me. They're much more realistic, and you get to see more of the beauty of the weapon design.
The pickup sprite (not pictured here) actually shows that this cannon has a stock... so where would that go, if you're centering the weapon? XD
The closest thing I can think of that resembles a centered Sovereign in any way is the multi-mode grenade specialized grenade launcher from Project Brutality... mainly because of the lens on it (interesting factoid... that gave me the idea of giving the Sovereign the behavior currently has).
