I didn't use the biohazard symbol as I already kind of overused it with my other contest subs.

As for the stripes, I tried that on both the barrel and the foregrip but it looked bad.

And the bile tip, my intention wasn't to make it actual bile, just painted to resemble it.

I might revisit the skin in the future, tho.

Yeah, I see that now. Still, it doesn't look particularly good. It makes the symbol not pop as much as it should.

What do you think of my other suggestions?

The symbol isn't actually touching the start of the barrel, that's just wear on the grip making it look like that.

The radioactivity symbol is too far forward on the grip. It doesn't look good that the "wing" clips into the body of the gun.

Also, wouldn't a Biohazard symbol make more sense?

It is a nice design however, but it could use some improvements. First off is a better position of the handle symbol (ie, not clip with gun body). Secondly, I think the goo on the end of the muzzle should be darker in colour, to more resemble dried up bile, as if you've stuck the barrel in the mouth of a Bloat and pulled the trigger. A striped pattern on the foregrip might also look better than the solid bright green you've got now.

The texture work is nice, but the idea itself dosent really look too good imo.
