Looks cool. 4th bottom-row, the recoils look a bit unnatural. The recoil energy first hits your arms and is mostly dissipated by counteraction from arm/elbow/shoulder muscles, meaning the gun usually jerks upwards from recoil, with a bit of upward arm flex to accompany it. When the gun has been used for a while, the recoil is familiar and the shooter will generally be able to hold the gun even steadier. The diagonal shot is a bit more natural, but I don't think there's need for leg movement either. Of course, different caliber guns may cause different recoils, but I think this at least partially valid for all pistols/revolvers.
Well... I'm not really a graphic 
. I'ts just a hobby and sometimes I create some pixels for fun :)
Wow, you haven't been to a site for almost 3 years and now returning with more action and zombies! Welcome back and why was the 3-year gap?
Strange, I though I had commented on this one.
Solid work, mate.
