Since none of us are actually seeing your snake, I think it's inappropriate for us to speculate on whether your snake is over or under weight.
People have very different perceptions of body weight, whether it's our own, our family & friends, or that of our pets. Some of us eat heartier & accept a more "robust" physique as "normal" & preferable, while others think anything over a very slender profile is "over-weight". (If you need an example, just look at the late singer, Karen Carpenter- she was always quite slim but her eating disorder made her see herself as "overweight"- and unfortunately, it didn't end well-she damaged her health.)
Anyway, maybe this chart will help you: https://ball-pythons.net/forums/cach...f42b352b68.jpg
