Have a look at all the images and explanations at the link I sent previously. Anti-crepuscular rays can vary in appearance and sometime you only see one main one although the others are there but much fainter. They are caused by light scattering from ice crystals and dust. The angle between the ray, you and the anti-solar point would likely influence the appearance of a particular ray but also the amount and size of the ice crystals and dust in the air.

Above I was only referring the the first image which has three rays that I can detect. I just looked at your original post and the second attached image shows a ray at a different angle. Was this taken from the same location at the approximately the same time? Where they eminate from is called the anti-solar point. Was the Sun behind you?
The first image was looking at the Western Horizon after sunset. The second image was looking the Eastern Horizon, only a few moments later. The orange/pink ray went all the way from the Western to the Eastern Horizon, although it lost its intensity along the way. I have never seen a ray before that goes totally across the sky.
