That's cool
An airbrush is a game changer
I'd recommend you get Chinese models
I got one that looks like this 10 years ago and it still works well for me although it's a bit loud
You need to get good at using airbrushes, getting an iwata won't make you good
I bought a Chinese airbrush and sucked with it so I decided to get an iwata eclipse, didn't solve my problems
Chinese airbrushes are perfectly good although they can be improved if they have sealing problems

Make sure you clean yours properly to prevent any future problems
DO NOT DROP THE AIRBRUSH WITH THE NOZZLE EXPOSED
Get an airbrush holder and learn to thin properly
I literally cannot imagine doing scale models without an airbrush, yes I feel sorry for the kids who either can't afford one or aren't allowed one but the truth is the truth
Make sure you get a decent respirator
