Thanks for posting, I want to learn this on guitar! You have a good voice and loads of potential!! You should get singing lessons to improve your breathing and range, seriously you'll be able to sing louder, sweeter and clearer with less effort, it just sounds like you're putting a lot of pressure on your voice which isn't good for you but it's still good! 🙂 I'm just speaking from experience, my sister has taught me a few things, even a few lessons about breathing and warming up your voice will help you a lot!
