To date, I have only seen one episode of "Total Drama Island", but I learned a lot from it. Namely, that the show has a lot of potential to be funny, but it's buried under a distracting miasma of shoddy Flash animation and ugly, angular character designs. Normally, I don't judge a show by its animation (for instance, "South Park" is very crudely animated and I still think it's extraordinarily funny), but with TDI, it's just too much to bear. Maybe it's because I watch "Foster's Home for Imaginary Friends" and I know Flash doesn't have to look this bad on a TV budget.
I tried to take a crack at reworking some of the characters to make them more aesthetically appealing. I made very subtle changes to Izzy, Lindsay, Gwen, and LeShawna here, but I tried to give them a stronger sense of three-dimensionality and solid character structure while still maintaining the basic style of the show. It's a delicate balance, but I think I pulled it off.
