There's a new tutorial on Psd.tutsplus.com, describing "the way of the pixel" by Russell Tate. It's describes the pixel art basic rules - good to refresh your memory. There are also some top pixel art tutorials links in the article.
Arjan Westerdiep is a pixel artist who creates beautiful, black&white pixel arts. There are some examples of his works on his website (as well as a very nice tutorial about basics of pixel art). His famous work is ic-project - huge illustration of a lighthouse made with only four colors! You can check the illustration here or head to the tutorial section of drububu.com.
Kevin Chaloux (also known as Kaiseto) is a young but extremely skilled pixel artist. You can check his gallery at pixeljoint or deviantart, or you might head straight to his page (there are some sweet tutorials).
There was a interview with Vital no so long time ago on Perfect Pixel Art, and now I would like to present a video he made. That's a recording of creation of a very nice skeleton pixel art sprite. Enjoy;)
Long time ago Computer Arts released a tutorial called "Building a pixel art world". (I guess I even read that in their paper edition). Although I disagree with some points of this article - it's still worth to check out. Computer Arts got a free pdf edition of the tutorial here.
