As I watched your video and you panned the passenger side door something jumped out at me that is likely more trouble than it's worth, but I think it would look really cool if the back top corner of the door were rounded on the same radius as the window opening. The bigger job would be rounding the body jamb area to match as opposed to having a "tab" filling the gap. Like I said, it's probably not worth the effort - the square corner just kind of jumped out at me surrounded by flowing curves.
