It would be pretty much impossible to make an exact replica. Even the Vinnytats jacket, as awesome as it is, has MANY things I could point out that are not correct. BUT there are many things that are right and I think he really nailed it. The most obvious would be the incorrect repo patches. All the jackets are different, and you cannot see all the jackets in their entirety, so your left with trying to look at them all to get an idea. Like I said, I didn't like that the movie jackets patches hung over so much so hung mine over a little less.
Don't sweat the small stuff, take your time, and most importantly try to have fun. BTW I'm now working on a 3rd one
