My first work with GS, the arm looks a littel "off" but otherwise i am pleased with how it came out, the idea was to make the sm look like he's paused to snap off a well aimed shot. Comments appreciated.
A well aimed shot at the sky? Lower the bolter angle a bit, and put some sort of bit (pretty much anything will do) under his hand. Also, just a thought, but do you think that the pistol would look good swapped with the bolter, so he is resting the bolter for a moment and firing a few pistol rounds?
