What is the chance that you like absolutely random shot? I would guess that chance is very low but it is not zero.
Before starting my walk with infrared camera I always make one random shot with the most contrast to check histogram. I do it often with visible light as well. When I looked at this test exposure image I liked it. I feel some jazzy composition in its chaos. I would never take it on purpose.

Random or not, I definitely would have taken it. I like the random “jazzy” composition. Mistake or not, you took it on purpose. You had a camera, you pointed at the scene, you pressed the button. No mistake. I like it.
