To see this style used in such a very expressive way pleases me a lot! The types of color combinations in these two images have always seemed to me, to be charged with a lot of potential.

The images are beautiful in an enticing way but also sorta' ugly as far as colors, etc., being pushed toward nauseating, (which highlights parts of the content emotionally and conceptually.) One result is that they are comfortably disturbing. The execution of the crowd being composed of more generic characters that lose most of what little identity they have individually, as a mob, is aesthetically ethical. They retain enough humanity for the viewer to buy into their existence in a context that's simple and subtle. Where the art marks* from the style are brought in, they verge on being too contrived but are saved by their authentic expressive use. I'll let others write about the main character in his environment.

Ok, that's just some stuff I think anyway.

*When these images are isolated and approached as successful fine art, these marks are usually justified by their execution, and by their by content at least, and some are archetypal, (or at least a priori and universal. - Ask me sometime if you want me to prove that quickly.)
