So Holly, you have gone over to the Dark Side!
I think your technique looks really good; you are getting a very nice effect. I think the one thing you might want to be careful of is, judging by these pictures, it looks as if it is developing a pattern. I think you might want to avoid this. I'm speaking of the almost "X" pattern on the back.
Not that I have ever done this, but looking at the hero props and some other folks' jackets, I think the best distressing jobs look as if they were accidental; the wear follows areas where one would distress a jacket if you were squeezing between rocks and other sharp objects; it ends up looking accidentally beat up. When one can discern an intent behind the distressing, it may look artificial. I am not saying that is the case here, but you might want to consider this.
I respect your courage in taking this on. I think it looks great and I am sure it will look wonderful when you are done. Good luck and please update the post with your progress.
