Valiant...
I am somewhat torn as to how I feel about this animation overall.
I commend the ingenuity, the original concept, and the strong attempt at a visually appealing presentation.
The sound was simple, which was appropriate. The visuals were ok, but it felt a little too 'pixar' for it's own good. There is a reason that the company hires dozens of animators, uses top of the line software, and throws millions of dollars into their budget.
In short, I like where you took this. Perhaps you were shooting a bit high visually, but that is what we should expect from our posters on newgrounds.
I would recommend working on the pace and the motion of the characters. When Potbot showed up on the table and his surface flexed to express himself - awesome. When potbot jumped off the table - horrible. He was floating, he was static in appearance, and that slower moment broke the flow of the animation. When potbot was driving over the water - awesome. When the sea lion jumped up it might as well have been a picture you cut out of the magazine and dragged in front of the camera.
