For this challenge I made 2 bowling balls, because the first one that I made had well over 9000 triangles, so it didn’t match one of the criteria of the challenge.
So I made another bowling ball, but, this it had just a shy over 9000 triangles. But, if it had any less it would look really jagged and in the lesson itself the ball also had a bit more than 9000 triangles, so I hope that it can pass this challenge.
Also for the second ball I followed this tutorial made by the Default Cube YouTube channel to make that texture.
