I'm still not sure what it is about this one, but something does feel a bit off. Maybe try changing the pitch a little and give him a bit more energy? He's helping a guest, so when you act, consider that scene as well. I'm sorry if this specific feedback isn't as helpful. I would say try different takes in your re-do for sure as well. Again, let go of how you may be viewing the character and try out different personas for him that you think may fit.
