Yes, that edit wasn't exaclty serious, just throwing hyper huge "soldinator" idea out there, going crazy with it

.
However, the gun part was serious. Your version is botheringly out of perspective - probably due to the part showing near the barrel. And i'd still angle the "body" of the gun upwards, while keeping the handle in the same position you have.
I'd tilt the head a pixel back. Maybe straighten it upwards a bit (as in "straightening his back, and the neck").
Also, i prefer the version with just one gun. The lower hand holding the gun doesn't convey enough MANLINESS, it's kind of soft. Lock his wrist, align the hand it with the arm, and pump the lower arm muscles!!! Or replace the lower machine gun with an army knife, the blade pointing downwards! (ready to KILL KILL KILL - even if there's no knife in-game)
The game is looking great, good luck with it
