Nice work. If you're into this sort of thing, you might also appreciate https://instagram.com/pxlpeeps/, though the style is more constrained, and the focus is on pop culture characters.
I'm also reminded of http://davegrey.net/tagged/pixel-art and http://iotacons.blogspot.com.au/ wrt small pixel art drawings from pop culture. It's amazing that you can capture character in so few pixels sometimes.
