Ok a few things.
The Art work was....uhh....how you say?....Bearly-able-to-stay-out-of-th e-toilet bad. I have seen a whole lot worst, so your not the bottom sucm but still. Good movie, it had some funny moments and teh good plot. Then you mess up in the art work department. Kinda original, seen stuff very close to this. But i think you could have done better. You could have added more story and make it longer.
So i give you a 3/5 and 7/10
What happened to CCC city?!
Concept is workable, but the art needs help. I would suggest practicing animation before finishing the next part of the series. Concistency is near vital to believable animation, and I noticed that the faces sloshed around unpredictably.
Your ambition is admirable though, and I pray will help you improve quickly.
Slow pacing until the fight scene, which was exceptionally short compared to the overall flash. I enjoyed the character development and inter-character dynamic. Not bad.
but that's all it is. The jokes aren't very funny, the art needs work, the animation is pretty average. The concept is good, but the execution isn't and the dialogue is pretty sophomoric. The voice acting is obviously great, but considering that line up it's no wonder. I dunno, I'm just not sure how this managed to garner so many views and such a great score by being so average.
Somehow didn't quite make it
This end of the world idea has been run into the dirt a lot here lately. Your art isn't bad, its just the story doesn't make it. Its to unoriginal, its too jumpy, and it doesn't smooth together at all. I wouldn't see a sequel coming out of this, I wouldn't know what you would lead on from this.
