Then someone posted a link to a blog covering the art direction and that included some concepts of the characters. And although they're pretty similar to the end result I find them much better than the models.
And that bothered me too, so I thought I'd have a go at sculpting a character from the concepts to see if they came out like the models I don't like and maybe figure out what is I don't like about the end result and at what point it changes.
Here is the original blog post.
And here's my sculpt so far.
