A nice lil toonie.
I tought it had a nice, simple story. The music was nice too! but there are many things that just dont feel right.
The first thing that really bugs me about this cartoon is how much (honestly) you guys ignored CONTRAST. And it is kind of a big deal. Often, the red guy´s pants and gloves kept merging with the background. You can do this, without using outlines, by simply playing around with colors/changing the colors of the characters clothes.
Second thing... the red guy´s eyes. Pick a design and do your best to stick to it. His eyes went from that cyclopean sonic-like eye form to being 2 separate shapes every now and then. Speaking of wich, remember how those eyes WORK. they shouldnt be shapes floating over the head, but MASSES inside of a skull.
I think both of those problems are caused by, well, bad character design. make at least a bunch of sketches from various angles so that you know whats going on with your character.
The sounds were ok because they help tell the story..., but were they necessary? I feel most of them didnt fit the action, even in the playful way the cartoon is supossed to use them. And they are distracting. They are like that idiot in the background when you are watching the news.
Right now i think you should focus more on your character designs, practice and practice to make the drawings FEEL heavy WITHOUT having the benefit of animation or sounds to assist.
great tips:
