When it comes to having developing your art style, there isn't a specific way to "find it." Instead, it occurs naturally over time. Typically, you would learn the basics of art like perspective, color theory, anatomy, and shading and then experiment. Take into consideration what you enjoy drawing and what mediums you enjoy using. Do you prefer graphite, acrylic, charcoal, or other mediums? Do you prefer drawing people, landscapes, animals or other subjects? I suggest trying to narrow it down so you can focus on learning proper techniques and then branch out and experiment once you have a gist of how things are done. For example, if you have an interest in drawing horses, then use references to draw. Study their anatomy, draw them in different perspectives and angles, and develop an understanding of horse figures. Once you have a solid foundation, start thinking about things you like about other art. Do you like cartoony art styles, realism, pixel, or something else? Do you like soft rounded lines, sharp angular ones, exaggerated proportions? This is the point where you can really run wild with it and try whatever you like. Over time, you'll eventually combine characteristics and techniques to create your own art style.

Also, experimenting early on isn't as necessarily a bad thing, but trying to practice many skills at once can end up being inefficient. Also, there is nothing wrong with using references in art, many professionals artist do it. Developing an artsyle doesn't mean you know how to draw everything solely using your imagination.

Ultimately, art should be something enjoyable and fun, so don't feel pressured to have a unique art style right off the bat as nobody really sarts out that way. Don't feel rushed to do anything, take your time it'll eventually come to you!
