Yeah I do definitely like the way the plainness and sort of unimpressed timidness of the expression works to give exactly the feel you described, the simplicity of the way it's stylized really works great too. It kind of reminds me of the art style from Ghost World, or what I vaguely remember of it.
Pretty cool. This is one of the better level collab submissions IMO, too bad you cant keep the red background for it but it at least it still works on the white.
