Don't get into the "Standard Shape" argument. No matter which description you go by the critic will use the other.
You can go by what Sasquatch says if you like. The pipe of mine he criticized has five buyers waiting for me to sell it. The one made to Sasquatch recommendations generated no interest from the buyers. Make what you like. Make what you and other pipe smokers you know would buy. I don't care who is right, I care about quality and what generates sales. I would buy the shape you have and not give the straight Sasquatch version a second glance.
Sasquatch is using the straight billiard definition.
Fujipub describes billiard as follows: A bowl which is two-thirds of a tall elipse; possibly the most common bowl shape, the name probably comes from the French word for "log."
Maxim Engle says: In its classic dimensions the height of the bowl and the length of the shank are the same or directly proportional 2:3. Max continues: The billiard is probably the most popular shape in any brand. It comes in an almost infinite variety of sizes. The short 5 3/4” billiard, the normal 6” x 2”, the stack billiard, the oversize ODA, the ELX size and the Magnum. It is hard to name another shape that scales so well. There are military mount billiards, paneled billiards, diamond shanked billiards, triangular shanked billiards, square shanked, bamboo shanked ones, with long and normal length shanks, LB billiard’s chubby billiards, flat bottom sitting billiards, rounded from bottom billiards, (Bo Nord), the slightly canted billiard, the lightly curved stem billiard and these are the ones that readily come to mind. The Canadian can almost be considered a billiard with a long oval shank or a Lovat a billiard with a round slightly longer than normal shank
Well ???? Is it a billiard because it is straight sided? An ellipse?, The ratio of bowl to shank?
I like the wine glass shape variation you came up with. While it does look like the back is a bit off from the front, there is also an optical illusion generated by the shank. Other than what may be an illusion, the rest looks very symmetrical. I also looks like you have some decent brier to play with. Pick and choose from the criticisms based on what the pipe smokers around you like when you show off your creations. Best wishes
