While I agree that Frodo and Sam need work...nitpicking about the lower lip might be taking it just a little too far. There's constructive criticism and then there's being obnoxious. I think, for the most part, Asmus enjoys the feedback and takes what we have to say seriously, but when we nitpick about such subtle things it makes it seem like the work isn't good enough and I think it has a lot to do with why they seem to interact less here.
Paint apps is a big thing, the sculpt of the face as a whole is a big thing. But lower lip? C'mon, man.
