I don't think it's negativity, but rather confusion.
Why make something so much more complicated than it needs to be?
As many people stated, the OP lives in Georgia--curious about the climate in his location, I googled Alpharetta and found that the average low through winter is right at, or just below 32ºF. That kind of weather barely even necessitates long bib tights, I wouldn't even consider thicker "winter bibs" until 15ºF or so. 32ºF doesn't even require winter gloves, just a thin pair of windproof gloves. At first I thought the rear box was to stop road slop from flinging all over the place (even though side spray has never been an issue in my experience), but it doesn't even snow where he lives.
He said he doesn't want to hassle with "extra layers," and wants to reap the "aero benefits" of his fairings--I'm no aerospace engineer, but from the looks of his project, he's actually managed to make the bicycle significantly
less aerodynamic than it was at the onset of this project. There are huge gaps everywhere, relatively flat faces at near 90 degree angles, and pockets to cause drag. He's probably spent more time conceptualizing and building this contraption than he would
ever (even after several years) spend removing "extra layers."
For 32ºF weather, I can't even imagine wearing more than a pair of full length bib tights, and a thin baselayer under some sort and a jacket. If he was really sensitive to the cold and wind, perhaps a windproof shell over the jacket. I wear those things regularly in the winter and it takes me
maybe 5 minutes to change, and I'm no clothing removal wizard (like this guy:

It's a very confusing endeavor. I remember someone on here in Seattle created a "cockpit" of sorts because he hated the constant rain/mist--that was a much more logical endeavor. I don't mind wearing jackets, and I don't like adding junk to my bike, so it's not anything I'd ever mess around with.
This just seems unnecessary. You're right though, it's his bike and he can do whatever he wants. More power to him.
