Let me tell you something...
First of all, I'm rather surprised that you made this animation with only your mouse. It was pretty good and it shows how much you've improved when compared to your other animations.
I'd suggest to invest some money for a pen tablet because it seems like you can do far better than now. The small ones don't really cost as much as you may think.
Seeing your other animations like Love on the Beach or Looking at my ... made me realize how much potential you actually have. As for humor, art and animation. I'd really like to see an animation made with a tablet someday.
Anyway, back to the actual review. Short and to the point: Your animation and art skills in this one really improved. I liked the timing and fluidness of it, too. Nonetheless, I know you can do much better. So 10/10 for you.
Keep up the good work. ;)
