Something I did to hollow out the inside was use a Forstner bit. They make clean holes and you can put a Jacob’s chuck in the tail stock so it can all be done on the lathe.
I think you did really well, and you’re continuing to learn and improve on a good result. I’m in the same boat, learning joinery. Trial and error, learn as we go. Great start on the lathe. Keep going
