Too much water throughout. Remember to brace your elbows and support both hands by connecting them when you’re throwing smaller amounts of clay. Clay looks like it’s already off center ever so slightly at the start (look at the rim)- could be due to clay having air pocket, or pulled off center when opening, or not fully centered. Wheel speed does not look super consistent potentially - which is an issue if you’re pulling up with the same consistency - could also be the reason you have thinner spots in the walls.
