Remember practice is key. My style was changing overnight everyday for the past year, I recommend highlighting and having other styles that you have master up your sleeve you you can catch people off guard. Also it always better if you have multiple different eye style because one eye may not look good on a certain OC so you can change it make sure you have eye styles that are able to for an example widen and narrow. I hope my advice is helpful, this stuff has gotten me from stick figures to today have a nice day!!!
