My First Ever Super Mario 64 16-Star Speedrun

This was my second complete SM64 16-star run, but I apparently forgot to hit record the first time. My first run was 49:09. This run was nearly 10 minutes faster, but there's still plenty of room for improvement.
This was also my first submission to speedrun.com. It was retimed to 39:43 by the moderator that verified it, and it is in 2944th place as of 12/21/21.
I'm using Project 64 v1.6 and running the Japanese version of the game.
