The black does look a little grey on my laptop screen, but mostly light balance. The bodywork looks absolutely smashing though, really nice. The front shock assembly is amazing, considering it came from one photo. Very well done.
One thing about the calipers, the pads look as though they are half on/half off of the rotor, and the caliper seems too far off of the hub centerline. Do the calipers sink onto the upright a little bit more? And yes, the metallic flake on the calipers is too heavy. I believe the calipers are anodized billet aluminum. Also the bridge spacers across the caliper are usually stainless tubing with long bolts, or cotter pins securing it in place. It seems almost cast as part of the caliper halves. Might be worth another look.
It looks so good coming together, what a fantastic build!
