That is gorgeous! I did a vogue 8340 a couple of years ago, intending it to be mostly a mockup, and every year I swear I'm going to make a new coat.. and then don't. (Not going to use that pattern again, I had a few complaints, and would really prefer to do something but a lapel cut into the front panel rather than separate, and ideally shoulder princess seams. I have a few patterns that are closer then the Vogue one I last used (I'm thinking Simplicity 2508 or 1732,) but somehow I haven't gotten myself to go ahead, settle on a pattern, and dedicate a fabric to it.
I find it so difficult to work out the details for a coat, I have so much trouble actually using my better fabrics; I want a coat to be more perfect than I should. I was frustrated as heck while I was making the Vogue coat, but still shockingly happy with it once I was wearing it. You are awesome for doing a coat as your own cloned pattern. And it's so beautiful!
