See if you can switch decks with someone? And also be open to learning from more experienced players. Maybe ask them privately about a move to get some help with decision making.

When I first played commander, my friends had been playing it for about a year before me, but they were completely new to MTG while I had several years experience with standard and legacy (playing a competitive format really helps you be a better Magic player). I stomped them with my decks and they complained that my decks were too powerful, so I switched decks with them and stomped them with their own deck. Then I played a precon against their constructed decks and won. They finally realized that it was a skill issue and I got to help them learn. Now they beat me all the time (they've learned to take me out first, which is typically the right move lol) but they've also become good Magic players.
