Yeah now that you mention it, it does kind of ruin the presentation. The rifle is actually an "upgrade" I designed to the pistol which I modelled and referenced from this with a few tweaks of my ownpersonally i would render not with a black background as its a little hard to see some of the detail underneath. I would also address the butt of the gun as it looks a little strange being curved.
Looks nice though, nice use of colour
Myth
I'll definitely look into that, I guess overall i should have thought more about practically with the weapon and its use.Do render with a black background (don't change the env color) but then save it out as a png or tiff and place it over another color in Photoshop or similar, so that we can see the details as myth suggested. The wire in the middle isn't working for me. Try routing it differently, maybe with intermediate fasteners so it's not just hanging off the side.
