Hi!! So when I'm belting I'm trying to get more of a fuller belt, belt it's coming out kind of swallowed, how can I get better??

Hi, Jace! If you're at the point where you can safely "mix" the pitches you want to belt, you may consider letting your larynx rise slightly, letting your mouth position widen, and making sure your tongue isn't retracting (pulling backwards and consequently pushing down on your larynx). All of those adjustments will help you achieve a more "chesty" sounding belt!
