I'd powder coat the entire setup in satin black so that it blends into the engine better.
It's leaps and bounds better than the crappy stock bracket setup on these engines!
If you had a drag car with just an alternator then I could see where this looks like overkill. But when trying to run A/C, P/S, and Alternator it gets annoying with the stock stuff and trying to make everything look decent.
What I like about it over the old setup they had is that it's a true serpentine setup with just one belt and they've pulled the accessories in closer to the engine instead of placing them out into the fenders.
