Lots of sharp lines and pretty good symmetry.
I think the thing that jumps out at me the most is that the top of the shank/stem is shaped like a hawkbill (reverse bend) and the bottom of the pipe is shaped the other way, and the net result is that the stem looks bulgey and the shank looks like it pinches at the bowl.
It's very very difficult to carry a nice curve through a shank, perhaps even more so on a thick short one - not much time to get the idea across.
If you go look at some "proper" bullmeese,
http://glpease.com/Pipes/Shapes/Bulldogs.php like lower in this page here, you'll see that the shank section is mostly kept straight - it's simply built on an angle, and really the shank doesn't curve at all. This is probably the only way to keep definition over the whole shape - keep it "English" in nature rather than a swirly pudgy fudged out Italian sort of treatment (and part of this comes from the types of machining used in both - if you lathe out a bowl and a shank, you get a bent pipe with essentially a straight but angled shank. If you grind the shank out on a shaping wheel, you can curve it and do all kinds of fancy shit, but often at the expense of that real crisp look that english pipes (and kaywoodies) have. This is the difference (one difference) between a dunhill bent billiard and a Castello bent billiard.
Here's some rather lurid examples:
