Great!
I can see you've just started making animations, and you're doing great so far! The action is good, the characters are okay, and your use of sound effects are great.
My suggestions would be to maybe add some personality to your main characters, maybe a shirt or hair and try to make the settings a bit more detailed. I was also a bit dissapointed with the ending, but whatever... Anyways, this could turn into a great series if you put a bit more work into it. Hope you get front page for today!
