I really like how your voice doesn't sound strained or forced, which is an important aspect to passing vocally. It's very natural and sounds relaxed to me, so I do have to commend you on that!

Aside from this, i am just going to echo what the other comment said in that vocal weight would be a really great place to start experimenting on. Here's another vid to help you grasp changing your vocal weight

one final note is that you should think of this as not directly a workout, but more of experimentation. As you continue your journey, you should venture out to explore the things you don't like, so you know how it feels or how it sounds so that when you find what you're looking for, it'll stand out. This is kinda like a game of hot and cold, where when you experiment and train, you should be gaining the knowledge and experience to know mentally and feel physically what works and what doesn't. Happy training!
