WANDERING EARTH - Machine Gun

What if Earth itself was the spaceship to save humanity?
---
The soldiers needed some machine gun so I was tasked with coming with different options for the machine guns.
The first pass was made with the smudge tool in PS,
the second pass was made by hand on a 50% print of the first pass,
and then back to computer for the 3rd pass. By then the production decided to change design completely so the fully shaded and colored version was made for my pleasure. The redesign's goal was to make the gun more discreet and very close to the actual QBZ-95 used by the chinese army.
