It is important to build your internet resume, in other words, get noticed by a partnership or start applying to them, and then begin working on your acting, sometimes it is best to have a good grasp on what you are doing.
Although i am a gaming channel i have experimented with acting and more, and found it to be more complicated than expected, voice acting really helped get a grasp, but i haf to take vocal lessons and improv classes to even capture a familiarity in my personal acting techniques. If you believe your raw behavior is acting, most agency's will ignore your request. In my unprofessional opinion, you have talent, maybe experimenting in just acting alone videos, and voice acting you could be a great actor, but right now i would focus on getting a backing and a deep resume of videos people can see when searching your name, that is gonna put you in a deeper brighter light than others.
Hope this makes sense, and i will be subbing your vids are good, good luck and hope you succeed.
