i'm a drag queen/performer, i get a lot of compliments on my makeup and i just kinda go for it! my suggestion is take a look at what kinds of makeup looks you're drawn to on other people, and see what you'd like to try on yourself. start simple, maybe just some eyeliner and mascara, something like that. there are definitely lots of YouTube tutorials for the basics, if you don't know how to apply makeup or eyeliner that can definitely help!
for eyeliner, i find that the ones that are shaped like an ink well work the best for me, but only if the tip of the brush is hard, not soft. i find that there's more control with them and i get cleaner lines. don't be disheartened if you can't get your eyeliner right at first: it has taken me literal years to get it down. it's hard! it's actually darn hard! nobody likes to tell you that part but eyeliner is tricky LOL. eyeshadow can be a lot easier at first, you can get palettes with a lot of colors and play around with them for pretty cheap. mascara is hard to mess up and looks great on everyone! just make sure you don't end up with big clumps on your lashes because that will make it hard to see and you'll tear up a bunch and ruin it
brow pencils are very helpful, i love them because my eyebrows are so light you can barely see them, so i draw on a lot of different eyebrows depending on what kind of look i'm going for. changing your brows can really change your entire look, but i know some people are very... put off by drawn on eyebrows? I don't quite get it because i get a lot of compliments on mine! it's a fun part of your face to change
due to my autism i cannot stand lipstick, i keep trying it but i just cannot do it, so unfortunately i have very few tips when it comes to lipstick, but i highly recommend what others suggested and see if you can find some easy tutorials for lip makeup! there's also lip gloss as well, which i also can't stand, but it's very pretty!
a lot of putting on makeup uses the same hand actions as drawing or painting. if you draw or paint, it will come a lot more naturally to you than someone who doesn't. i'm an artist and a painter and i found that i was just quite literally painting and drawing on my face and it helped me get a better feel for it! i also literally use a paintbrush (not one that was used for paint!) for my eyeshadow and it works great, it makes it feel all the more literal which is fun.
good luck! i know that was a lot of words. go slow, build yourself up, look to others for inspiration and don't be afraid to look up a tutorial if you're totally stumped!
