I really like the brushing, and think the render goes very well with it. The double border looks good, I think what RnC12450 said

Although i say the render should not just be in the middle
goes with most but it could work out but having a render placed in the middle sometimes changes the effect I think it goes ok here. I think your opacity on the bar compared to the rest of the sig is a little to strong, I mean it does stand out but sorta to much for everthing else.
