nice pipe!
I'd change that:
1. Canonical billiard has same-length stummel and stem. It seems your pipe will become better with shorter stem.
2. Stem tapper looks better if starts on shank. I mean shank is not to be precisely cylinder.
3. I'd make a little butt-liposaction.
4. Billiard will be more fine with waist on stem.
All imho.
