If the gun is old (it's an old model used in ww1) and the blood splatter has been caused by the user of the shotgun having killed someone (or something) by hitting them with the shotgun butt, you'll have to change the following:
- The blood stain of the gun neck needs to be larger, a bit rubbed back and forth, and have a larger surface (the hand would need to firmly clutch almost all around the neck). Possibly add a hand-shaped outline of darker blood, created from the blood that's splattered on the hand that dripped down to the wooden surface.
- The wood looks too blurry -- Sharpen it and tweak the normal maps because the wood's shape looks too unrefined to have been shaped into that design, let alone used for such a long time.
- You'll need to add blood where a person would grab the gun to transport it (not in a shooting position), and possibly in some other places because blood is liable to produce a large amount of random stains.
- Scratches from pump action, because right now the pump grip's lead looks like the pump has been attached just now, and slided in without touching the sides
Overall the piece looks like it could use an AO pass and also add a tad bit more saturation, blackness and dirt.
Long post again huh?
