I like it, but it leads one to think that the brushed background is confined to the lower-right corner of the sig. Change the intensity of the lighting, or, if you just used white backing, lower the transparency so that some of the background is visible behind the render. The lens flare was a nice touch, though. Overall, i'd give it a 7.5/10. Not to sound superficial or anything, but "Keep up the good work".
