How do you know there is no endpin at the bottom? We can’t see the bottom of the instrument in this image. Not all cellos have endpins, by the way, Baroque cellos don’t have them.
Octavia herself is wonderful, as is the detail on the cello, but it’s way smaller than a cello should be, and is missing the pin on the bottom (should be extended for playing). As an idea, when seated and not angled, a cello’s body should come up to her neck at the very least, if not be closer to the top of her head.
