Volume is perfect, but you sound like you’re announcing in a small room. Without going back over five forum chapters, what is your studio? The idea behind recording in a closet is to leave the heavy coats and jackets in there with you. If you take everything out, it’s going to sound like you’re recording in a box—which it does.
Echoes—sound bouncing off the walls—is really difficult. There’s no good way to get rid of them in post-production. You have to do it in real life. You are also warned against trying to fine tune your voice quality until you resolve this, because most of the fixes will change the tone of your voice.
Most home blankets for your bed make terrible soundproofing because they’re too light. Same with FedEx or UPS packing material. Packing’s job is to take up space and not weight anything, the opposite of what’s needed. You don’t need expensive sound panels, either, although they do work. Plain furniture moving-to-a-new-house blankets work just fine.
I made two blankets and some plastic pipes into a small sound studio as a test.
It does an OK job on street noises, but it kills room echoes.

You can buy those pads at a large hardware store and hang them from your room walls. Lay one on the floor, too. You can have floor/ceiling echoes. Note there’s one on the floor in this shoot. The heavier the pads the better.
That was a voice sound shoot for a movie. It’s hard to see in that photo, but those walls are double pads.
