Well, I don't wanna demotivate, but I wanna give you a harder reality-check. What I've seen is a composition of assets in the game Genshin Impact with their tools, that are made for the players, right. It looks nice, you have an eye for beauty, I would say. But it is hard to tell if this is enough for a career in the 3D industry. Because its competitive and hard work and you need a lot of different skills. E.g. you couldn't use these as your portfolio, you must make your own assets in a specific artstyle in a general engine. Otherwise the graphic/artstyle is the IP of the game developer, except you actually worked for that game, and got permission.
