Having an unique art style comes from two specific elements: Stylization and drawing habits.
I dont think I have to explain it, but stylization is when you take a different approach on the base concepts of fundamentals, it's an important aspect of art that you sometimes do without realizing, but once you realize, it can become a tool for your art style to develop, even if it's something as small as making mouths a certain way or drawing hands like this instead of like that. If you want to explore an art style, think outside the box in regards of your fundies, observe different artists and their ways of doing things, work in ways you find yourself comfortable in.
The other element is a bit less of your control, they're your drawing habits, which are essentially very small details in your technique and process that certify a work as yours, these are more easily noticeable when the art style itself isnt so unique or when you try different art styles, your technique will leak through any art style you work with unless you manually work it out.

Actually, the only elements you can recognize him for are just the drawing habits, anime art styles are saturated and this one in particular isnt very unique per se, so the only thing we can latch onto are the very small drawing habits, like the way faces are drawn, the shading and tones.
>I want to be like the artist in pic related where anyone can instantly tell who the artist is.
First of all, dear god you dont want to be this guy lmao. Second, the only reason we (I?) recognize this guy is because of the drawing habits and because he has been the center of schizo drama for several threads, one still ongoing on this very day, so of course in the spam of his art, some are caught onto his drawing habits and the anime art style. Point being: Being able to recognize his art of all people is not a great achievement.
Also, please let us not derail this thread with madness...
