I can say with confidence on my end, that you are relying to much on your throat for your sound. And the top of your throat at that. Definitely work on producing the tone lower with a lot more diaphragm power. It will probably take a while to correct, as you'll need to basically reteach yourself, but it's definitely doable. Also, I personally don't see a problem with the style you're already using(reminds me of gorerotted a bit), the advice is just based on what you want to sound like.
