Here is a little update with my Complementaries characters. I got bored after rigging them so they sat there for a while doing nothing, or perhaps I just didn't have a reason to animate them.
Anyway, I found a tune I liked that I could imagine them singing, 'Mohair Sam' performed by a European Band from the sixties. I liked the naive singing style with them singing an american song and not quite getting the pronunciation down. I'm going to try and do the whole song, but for now here is the first half minute.
