New VALORANT player - Which agent should I unlock first and how can I improve my aim?

Hi everyone,

I recently started playing VALORANT and I'm about level 10. I have enough Kingdom Credits to recruit a new agent, but I'm not sure which one would be best for a beginner.

Right now I mostly play Brimstone because his abilities seem simple to understand.

Which agent would you recommend unlocking first for a

new player and why?

Also, I'd appreciate any tips for:

1)Improving aim

2)Crosshair placement

3)Movement and peeking

4)Common beginner mistakes to avoid

Thanks for any advice!
