Can I confirm? Well, I don't truly know... I'm just making an educated guess... but what you've drawn seems to be more correct from the few photos I've seen and the way it looks in the graveyard scene. Maybe not quite so long, as the first photo I posted looks to be pulling the entire coat back some. And I don't think you should lower the front so its dragging -- it seems to just touch the ground so when he's walking he doesn't trip over it -- but there's more material flowing in the back end.
I see now on your cape how it can fold over at the shoulder and appear as two levels ("a shorter and longer cape") -- the way you have it makes much more sense.
