Well, I think the main issue is that the artist in question has a specific style that he is bringing to the work, instead of bending his style to match the stated aesthetic. His personal style is more cartoony and "fantasy" versus the straight lines and "sci-fi" nature of Neon Noir, and that is throwing it off for people. I get it.
But, this is Scott's game and it's going to look how Scott wants, so ultimately everyone is just puffing hot air to no end. If you don't like it, don't buy it. I don't think they'll have much trouble selling the first run.
