This looks sleek! Good job, especially for a first! It might be worth taking a look at something like Material Design 3 to help provide a really nice UX.
If you do take a look at the Material Design website, you’ll see a section on elevation. Which, speaking of, I personally think the dropshadow from the buttons on the right are a bit too far.
Nonetheless, I really like what you’ve done. Keep it up!
