Exellent with a little work needed
Great job! The animation, art, coloring, shading, ect. were nice, crisp and relatively smooth.
The fonts and visibility of the text could be worked on. Be careful of contrast with the background and the fonts.
The only other thing you could work on were the voiceovers. It was nice and clear but sounded a bit over the top. Perhaps too much yelling and the dialogue was poor.
Otherwise awesome job! Tweak out your next animation and it'll be sweet.
