A+ for effort !
If you ever make 50 pipes, you will look back at this and see everything wrong with it. But you did a damn decent job for your 3rd pipe and an even better job of listening to and implementing advice.
I wouldn't worry about making changes to this pipe, but what you need to work on next time around; You still need to discover how to shape a billiard bowl. Just keep working at it and eventually you will figure out where to put all the curves so they work out right.
Concentrate on that shank/stem junction. It needs to be a perfect fit with no sloppiness from sanding them seperately.
There is still a dip in the bottom line of the shank, where the shank gets skinnier, then thicker again under the bowl. That bottom line from shank to bowl should be straight with no rise in it.
But really, good work.
