Any tips on how to get better at Valorant?

Practice aim -> movement -> learn characters abilities -> learn how to counter characters via abilities or out-aim.

Also learn a lot of lineups/tips on how to do really good on characters you enjoy.
I don't even play it anymore but these are good fundamentals, pretty much can be used on any game in the FPS genres.
If there's no abilities like CS then replace it with grenade lineups.
