It's not that the MC towers over everyone, unless you make them tall, but even a "short" lamia is rather bulky compared to standard humanoid races, which in turn leads to some difficulty maneuvering on occasion. A good example is when the MC is in the wagon on the way to Reabelle and tries to turn around, she is so long it makes doing so difficult.
That said if you can point out where it read like that so I can adjust it I would appreciate it. Smol snakes shouldn't be seeing things from to high.
Your MC sounds adorable!
