It depends on what you intend it to be. As with all of art, if you set out to write a sad song or paint a sad picture and it isn't sad, you've failed. But, that doesn't mean the song or painting is bad, just unsuccessful at meeting your objectives. If you wanted this to be a traditional poker, then, mmmmmm, not so much. But, it's cool none-the-less. Sort of avant garde, so to speak. If you wanted to make something unique, then it's a win.
Do I like it? It's cool looking and unique, but not something I would want to smoke. But, I can definitely see someone finding it appealing. I definitely like looking at it. If it were to be more traditional, with a shorter stack, it probably would come across as looking mediocre for a poker, just another traditional shape. So, maybe consider just leaving it this tall and go with the unique pipe look.
