Not really an illusion, it is the clouds reflected in the back windows of the car being reflected into the wing mirror (hope that makes sense).
A busy day, with too much of it spent in the car, and as it was the first day of school here, the traffic was a little on the heavy side. At least I was not driving.
And it is square for the square September challenge.
Very nicely composed in a square. The car is in square 8 at the bottom, if you are counting! And the eye moves around. Simple and bold with few colours give it great impact. Well done.
Great effect blending reflection with reality. For me I find the crop just right...I'm not too distracted from the main "V" that plummets down through the image which is excellent since that is where you want us looking I presume. Very nice!!
