I think you`ve over sharpened the render and thats why it looks LQ, You should of added more to this sig it would of been very succesful.
Also the text is Slightly better.
7/10
it looks good but the top is a little too bright and needs some more effect added to it. you text is a lot better than it has been in your last few sigs and you are just gradually getting better..........7.5/10
