Nice looking bowl William. The only thing I would change on it is try to keep the wall thickness the same from the lip down to the bottom it may mean using a tenon rather than a mortice then remove the tenon. These are things that after a while will become easier to do.
I very rarely use carbide tools even when doing hollow forms. With a bowl gouge, I feel you can get a much better finish and reduces the amount of tear out especially on softer woods. It pays to get someone to show the best way to use any of the tools for woodturning. I have 4 bowl gouges one for heavy and deeper work and the other three with different grinds.
Most of the time I will start sanding at about 240 grit that does not mean that I will not go courser
