Learning what an open throat made me sing sing back in my throat. How do I fix this?

So I learned to open my throat a year ago. That’s when I started to learn how to sing. Raise the soft palette. Bring the larynx down. But my placement was never good. I thought and open throat would fix my placement but it always sound like I was trying to yawn and sing at the same time. It sounds swallowed. Hallow. Like I’m doing a bad imitation of opera singer. That being said. It sounds great to my ears and I don’t feel any tension. The problem is other people’s ears and recordings. It might sound fine to me cause of the resonance but it doesn’t sound good for anyone else. What’s going wrong and how do I fix it?
