I don't agree with the term shitphoto because every photo is taken with a reason. The quality may not be very good, but it captures a moment.
This quote from Karl Lagerfeld perfectly explains it.
"What I like about photographs is that they capture a moment that's gone forever, impossible to reproduce."
As I read your post, there is really an idea behind the photo. And besides, I like the combination of colors too. I see why you took it.
Just like you, I also have eye for my environment and take pictures of interesting things.
