One word: Awsome.
The animation was great. I like how you used sketchy type drawings.
I like the way this is because when i animate,I hate colors.
Just, black.Your style is creative and the timings wer perfect.
The part where they look and quickly tun there heads was a little, Ok alot, abunch,HORIBLY fast.
But that is just one part, The rest is perfect.
Keep up the work!
