I would add the front bumper segment. If it will fit at the same height. I can't tell from that photo.
Stylistically the door part ends at a "forward slash" slant. It might also look nice to have some sort of continuation of that theme on the the other end. I think it would tie up the two ends better. Maybe trim the length a little to fit that area before the front bumper side duct begins. That should give it a nice factory look.

Again, if you don't like the front piece you can just peel it off. I paid $80 from the UK graphics guys for all four pieces. If you do install that front piece be sure to have it pointing down a few degrees. Since unlike door the bumper is not flat and actually turns in, sticking it flat (with like a bubble level) will make it look like its pointing up when you look at it from far away.
