Ok, here it comes. I'm tired (no sleep, long day at work) so I hope everything I say is coherent enough.
I can't tell much about the overall model and shape at all as the measurements are apparently completely custom. What does seem to be the case is that the jacket is too short on you.
Remove chest pocket.
Seams sleeves should NOT join the chest seam. Way off.
Either button caps are too big or the cuff is too thin.
Button knobs/studs are too big. Something that's always bothering me with replica jackets.
Zipper size seems to be 5 instead of 8.
The ribs of the ribbed fabric are too big. Need finer knit. Ribbed fabric of the lining looks good. Ribbed fabric of the outer shell and the inner lining should be exactly the same.
Curves flaring outwards on the back are way too curvy. The shape is totally off.
No stitches on the ribbed fabric at the bottom. Only on the suede.
It appears that the shoulder seam running from neck to shoulder/arm opening should be lower. (4 cm from fold line when laying flat).
Here are a few pics to back up my comments.

To be fair I don't know what to say or what to feel. I mean, literally everything has been documented and noted down, multiple original jackets have been photographed and measured to death and there is hardly anything left to document and still there are some very obvious mistakes that in my opinion are totally unnecessary. There are also some nice-looking bits but seeing as the original jacket is well-documented I kind of take that for granted. I know that it's 'merely' a prototype, but I hope you do get what I'm saying. I don't mean to be too harsh or blunt.
I can't say much about the colors. In the pictures the jacket looks quite a bit reddish brown. I would be happy to help out with the colors were it not for the fact that I'm still waiting like forever for something to arrive or even be sent to me...
