To be your first animation made by you, it's not bad at all, I also liked how the Japanese structure was completely in 3D, so I hope that one day you return to see more animations made by yourself!!!

Ending was pretty solid and it looks pretty pro grade for a first attempt. I loved the 3D rendering esp of the japanese buildings. I think you have serious potential and am looking forward to more submissions in the near future

Love the ending :D

Huh, wow, animation is honestly pretty decent. You say this is your first cartoon, but it certainly doesn't look like it (leagues better than the first crap I made when I first got Flash CS3).
w00t!
