I decided to show the entirety of my results for the sake of consistency, but I want to highlight the zoomed in screenshot I’ve also added.
Since these were specified as regulation bowling pins, I wanted it to be as accurate as possible, and the fact that the bottom of the reference image had sharp edges felt off to me. So I did some research of pins from various angles and considered how pins interact with each other. I decided that, for the sake of realism, it would be better to add a slight curve to the bottom, which I made work by scaling and shifting the curve-points.
