You are right that photography is an art and not everyone can learn it, some people take very professional pictures at different angles, they take such pictures then they look amazing. You are a very good photographer. In the first pictures of a bull, it looks like the bull is looking into the camera, you have taken these pictures fabulously,

The light and angles in your pictures are absolutely correct. You showed fan in the last picture is exactly what you said. In olden times, when there was no light, people used it to get light at night.
