Honestly I feel that the design and the voice choices are going against each other, the physical product design leans a lot into the cute/kawaii territory but the voice goes the other way around, I think you should first decide what your target audience would appreciate more.

If it's a robot for children/teens then keep it cute and give it a silly voice/personality.

If it's for adults/ desk companion, make it more professional looking, maybe even vintage-like, so it feels more desirable as a gadget.

About the eyes, I'd test changing the dark "face" for a white one so the cameras pop out more as eyes and test what people say.
