I am very happy with these vultures. I've always wanted to make a mobile with a group of them in much the same situation shown here, along with the carcass and a few more flying in a circle above. The main reason I haven't is that I've always pictured it in a grassy plane, which would be rather difficult to depict in a mobile.
I also like the very cheap cartoonish shape that I used for the carcass. I think that adds a nice humourous aspect to it.
