Not really liking this, i don't like how the two colors clash. I think it would be better if the left side was Orange too. I'm not sure if this is your fault though. Because if you used a stock you cant really help it, Maybe a Black and White version? With most of my sigs i add a black and white gradient map and play around with some other adjustment layers to see if it looks good in Black and White, if not i just hide them
