TBH I did my old grill surround satin black and it looked crap. The car was medium steel blue and didn't suite the black at all, and that had black eyes and a modded bottom grill. I just didn't think it looked right.
Think yours looks spot on as it is. Maybe black eye the fogs and bottom grill?
Lucky to having the nice shelter of a underground car park, next thing on my wish list is a house with a garage lol
