I think the wrist bend looks unatural in that last one, it is bent too much. Either change the way the top hand is holding the gun, or go back to that first version you posted with the gun centered in the middle.
It is not a bad idea, but I think you should post a new thread for this weapon somewhere else, rather than just posting in thread about something completely different.
Xm, can you explain in more detail why i should change the way the top hand is holding the gun ? From Right side to the midle.Is it looks more realistic in the center or more baddass ?
And what's wrong with the holding the weapon in the right side ?
P.S.
This weapon can't be implemented in simple killing floor, many aspects should be changed, to give a balance for this gun. Its Kinda Epic Stuff, so territory and monsters on it, should follow the terms of.
If you will add balance not in the gun but in the monsters(in many aspects of them) it would add much more interest to play, instead of balancing the weapon for the monsters.
This why i've proposed to be a mod. Cause for sure, present gameplay can't admit this, its to typical - Complining who would just kill more mobs, with any Perk and same gun. Just imagine 4 owner's of M134 and plus some perk bonus, its ridicoulous.They would be tired very quickly.
