It's a peaceful place for a walk and lots of wildlife to see.

I too use a smartphone and it is super handy because we have them with us all the time.
The quality of smartphone images and video is amazing.

The main issue with smartphones is that everyone uses the same filters etc so they all start to look very similar.

The advantages of a DSLR is that you can set the quality of so many different elements that you can make very distinctive images and videos. Cinematic, bokeh etc.

Not that I'm an expert but I do enjoy playing with the camera's many options.

Shooting in the raw format allows you to pull out so much more detail from a scene.
