Pixelated Avengers, He-Man, and Adventure Time Art by James Boorman
Pixel art is modern day impressionism mixed with the previous limitations of computers and consoles. Artist James Boorman has created a series of 29 characters from comic books, movies, TV shows, and video games. It's amazing how much of the characters' personality and design translate into a 25x25 pixel grid. Boorman pieces are not true 8-bit because he's using color variations beyond the technical limits of the 70s/80s technology, but they are still well rendered.
