OK, I did it. I submitted my own idea to Oh Yeah! Cartoons. I mailed in my submission and they received it yesterday, so now I just have to wait for a response.
They said that they only have a few spaces left to fill and that spaces are going quickly, so my pitchboards are very rough. Not at all clean and polished like SpaceGhost2K's and Jabberwocky's boards. Time just didn't permit it. I just provided enough information to get across the basic idea and tell the story. The rough quality of the boards may hurt my chances, but I would've kicked myself for not even trying.
