I've gotta go to bed, but for one neverever save as .jpg or .jpeg as it distorts your file and ruins the pixelart-y goodness of it. Second, if you did save as .png or .gif or another clean format, your host must have destroyed its pixelly goodness.
Despite the image distortion, you should look up "pillow shading" and learn to determine a light source to avoid that problem.
I sleep now. Good luck!
