Danny Kneip:

Pretty stiff movements, but a mostly believable performance overall. I noticed that you got at least one blink in there. Consider blinking every time the character refocuses his attention or turns his head. Video reference can help your puppet immensely!

Ian Alexander Hanson:

Definitely like what you're going for.

arms disconnected from body, and hips / spine are not involved enough in the actions.

Nathan Younger:

weird neck movement, mouth doesn't match the intensity of the words.
