hey! I think watching films and noting aspects you enjoy in the film or subjects you enjoy visually would be a good start. My opinion is that you want to start off by doing things you enjoy and exploring the different skills that come with it. To build up technically, watching youtube videos or BTS videos of big films will help build your understanding of how scenes and shots are created. (This will then get annoying as you will recognise these methods while watching a film hahha).
Please do reach out as I am also a university student and would love to try and grow with you!
