I don't know the specifics but I'm fairly certain this wasn't "hand-made". It was produced overseas or in some type of production facility. I really doubt it is possible to make this with a "2-man team" in someone's home. My assumption is that Jazz modeled this in CAD or some other sculpting program and the files were sent to a production facility and produced there.
If this was handmade with care, you wouldn't, or shouldn't, have a sloppy paint application like what is shown in the video. The product shows all the hallmarks of being produced in a factory with shortcuts taken in the paint application.
I'd be more willing to overlook the poor details if it WAS produced in a factory, but if someone passionate about building 'hand crafted' this item, I'd be much more disappointed with the final product.
On a separate note,
looking at another video review was even more concerning as the front of the cockpit didn't have screws, but suffered significant damage in shipping. I'm curious why one cockpit has screws in the front and the other does not.
EDIT: I'm wondering if the above reviewer was accidentally shipped some pre-production sample or something.
This other review doesn't have screws either. That might explain the crummy paint on the first example.
