If you don't like that image remember that it's specifically the Desert Rangers.
And it says nothing about what an isometric game will actually look like, in the end. The style of the game will demand much different visuals than what you can get from that sort of concept art. Planescape: Torment's cover with Nameless One's leering blue mug - or that alternative with the various 3D models - didn't indicate what the game itself was like visually, and I imagine it's similar here. It just helped to establish the strange, eerie tone.
Speaking of Torment, that game was - and still very much is - visually brilliant:
Doesn't that game still look absolutely incredible? I would honestly be happy with visuals on that level with these Kickstarted cRPGs. That'd be even better than what I'm hoping for.
