Very cute! The voices reminded me of Terrence and Phillip!
However, I also watch animation without the sound, just so I can focus on the animation. Without the sound, the scene is very flat... you have no idea what is going on between the two characters. I think this would be more effective with some variety in terms of the motion and the framing.
