It was...
It was quite catching, actually. Do mind the running, the physics, and try to make the sounds more intense. You may think you're lame when you're yelling in your microphone, but the result is way better. Just go nutsy.
What I find intregueing is the talent I see. You see, when I started watching Castle or Xombie, I saw no interesting or outstanding work, but just fine work. Good. Acceptable. I see that here too. Knowing that it's gonna end up a serie, you're set to become awesome, just like the annimator of both Xombie and Castle. (if you haven't seen 'em, check them out).
You've got some talent. Just keep working on the physics, and really, the castle physics are the best I've ever seen. If you want some inspiration, check out castle 2 or any of the parts of 3. Good work, looking forward to Gi-go 3 =)
