The red and yellow look like war paint haha... but seriously, the red and yellow in the sig just kill the flow IMO, it doesn't work well with the green. That right end looks very empty compared to the left. Text is solid IMO, but could be close to the render IMO. I think desaturating it a bit might help if you're set on the colours.
your best, but whatever you do to make your sigs look grainy and dark is bad. if it's a stock then just delete it(I'm talking about the left side).
but other than that, the text could be moved closer as brinka said, and maybe desat a little.
