Hi. It's not an easy field, I'll tell you that. It'll take a lot of practicing before you can make something of production quality.
With static pixel art you have the challenge of drawing something good; with animation you have the challenge of drawing it good, several times.
1) Pick the right pixeling\animation tool. You need to get the software interface and hotkeys customization done with and out of the way. Once you do that, the software should allow you to work without distractions.
Nobody can choose a program for you, you have to 'feel' which is best for you.
2) An artist is as good as the reference he uses. Study animated sprites from professional games. Record yourself with a camera performing the moves you want to give your sprite, and go frame-by-frame analyzing motion (seeing how you move, how fast things change from frame to frame, how they slow down etc.). You can use Media Player Classic - Home Cinema, as it has frame-step controls.
3) Study animation theory and how it applies to pixel art:
