I ask for some help in the Perspective area since its a major weakness.Construct offered me a test. I kept it pretty simple with a modified front end.

Well - i think you have to modify the trapezium on the front bumper. In the latest VW cars, the bumpers come down perpendicularly to the ground. So this is the trapezium:

If the bumper came down perpendicularly to the ground , the angle ADH is equal to BCK when it is on the bumper.

If the bumper came down like a ship, the angle ADH is greater than BCK when it is on the bumper

If the bumper came down like a snowplough the angle ADH is smaller then BCK when it is on the bumper

I hope to have helped you

Yes this helps. I just noticed the black lip is all wonky too. Uuggghhh.

It's hard to tell which bits are new
I can see the splitter is, and that's actually not that bad - just needs the bottom right side moving up a tiny bit, and the top of the new vent on the left needs skewing a bit to match more closely the angle of the sideskirt..

But overall not too much of an issue
