Maco,
It looks pretty nice the way it is, but if you want to tinker with it a bit you might want to try doing the guide wrap in black and halfway through it put a couple of turns of silver metallic in and finish with the black? Or you could do it something like this? If you can understand it? the entire area aready has the red underwrap and the 4th line in on the guide wrap would be silver with everything else black.

Just have to play around with it until something catches your eye!
