Why are these film photos brighter than digital photos taken at the same time with the same settings?

There is the potential for variations in many of these steps, but the first one that jumps out at me is that you used the same ISO, aperture, and shutter speed for both exposures. Also, answering your ...

My film didn't fully develop

It looks like your film was developed just fine. What you're seeing is fogging by an unwanted light source. The sprocket hole 'ghosts' are quite indicative of this. It seems the film was fogged when ...
