The more you race the more you’ll get to know the courses and the regulars in your field, and you’ll get to know their abilities. You’ll learn who you can drop, who’s stronger than you, who’s wheel you need to be on (as well as who’s wheel to stay away from), and when/where to make your move. I’d personally spend these first races getting to know these things and use them to inform your tactics in future races so you can, hopefully, win.
Finally, you stayed upright in a 4/5 race… I’d call that a good result.
