I really DO NOT like the art direction this game is taking with outlines.
Outline works well when one wants to create "cartoon" like feeling, like in the Legend of Zelda: the Wind Walker, where you have a feeling that it is just drawn 2D picture in a sense. However, elemental is unquestionable 3D non-flat world and models and complex textures. To see outline here is UGLY, it does not make it cartoonish or drawn at all; it just makes it ... ugly.
I remember one of the first screenshots, the outlines were really thick, and the ugliest, later screenshots (we do not see it in beta) have less outlines and thus better.
However in beta, things like 3D models in the menus have this outline that I really do not like. I understand that tastes differ, but I just think it is very incompatible to have obviously 3D models with those black outlines trying to convince that they are drawn. It just does not work. The graphics should be way more simple and cartoonish for this to work, and I do not think that this is the direction you want to take.
