i kinda like what you've done with this, ive seen alot of sigs with this but alot of them dont look great, few pointers remove the blurry lighten effect smudge the background more cos the round smudges are to obvious remove the golden glinstering effect on the left side of the stock goodluck and well done
The smudge is kind of bad, but the effects behind the render are good, the render is also really low quality
