Hi and welcome from the UK. So before you even get started, lets make sure you are properly set up. Ok, so firstly what kinds of stuff are you hoping to paint/paint on, what paint do you have? (to make sure its suitable), what compressor, and does it have a regulator and water trap. Having the right set up will make learning much easier, and knowing this will help folks advise you. And as mentioned the airbrush tutor vids will get you started, from how to hold it, to exercises, and first projects. Shout out any questions, and show pics, even of practise, or things that have gone wrong, folks can save you a lot of time if they can see any issues, or even reassure that you're on the right track, and there are no trolls here.
