To me it seems the shank/bowl tranistion is a little weak, and could use some further definition
What I mean here is that if you took off a bit more wood from the bowl at the shank bowl junction, you could create a sharper shape. Perhaps this is just my taste coming through, as I do tend to favor pipes with a very distinctive transition.
As well the heal seems a little swollen, i.e. seems to bulge out below the shank, making the lines a little incongrous.
With this comment, I was highlighting the way in which the bowl continues to slope downward on the bottom. Take a look at an old GBD apple (GBD rules when it comes to classic shapes) Even in a bent apple, the bowl stays pretty much in line with the stem.
Again, perhaps this is just my taste coming through.
Overall, I think you have an awesome pipe. I love the black and tan finish. And it definatly looks like an apple shape to me. Rotten apple is cute btw. Go with it.
