You asked for a critique of this pipe, so with the intent of giving you some honest feed back I have the following.
I think you made a good start on this pipe but, frankly, you stopped way too soon.
The pipe has no definitive shape. Is it a Pot? A Billiard? Something in between?
My recommendation is that you develop a definitive design and draw that design on the block before you start carving.
Then, stick to that design unless you make a mistake or run into a flaw that requires a design change.
I also recommend that you pick a well defined, traditional shape to start out with. A Billiard is a good choice.
Take this pipe back to the sander and remove a lot more material to reveal the shape that is hidden.
I suggest this:
Keep cracking at it. A lot of beginner pipes have the same kinds of issues. And part of becoming a pipe maker is training your eye to see what a good pipe looks like.
