First off, use [img] tags when posting an image.
you can upload the images with site like imgur or minus
Also, I think DA distorted the image, as it's a bit blurry, but from what I can see, this can't really be defined as a sprite given its qualities. Take a look at the Spriting Dictionary here for resources.
Bottom line, pixel art is the practice of careful individual pixel placement to create a desired effect. From what it looks like, this was done with a brush tool which auto Aliases (the creation of lighter pixels by it to blend the two colors), usually cluttering the already small space. I'm sure there's someone here who can better explain, but first things first, it needs to be uploaded without the distortion.
EDIT: Ninja'd. Oh well.
