I highly recommend this Tutorial
TheHayleyDolls is incredibly talented, and in fact it's her dolls that taught me how to pixel. Remember, NO ONE is naturally talented at this. We ALL have crudtastic dolls from when we first started dolling. It's a learned skill, one that takes practice. I suggest making your own doll from a plain standing base (not the one you posted in this thread, that's much too advanced for someone who's new to pixeling). When you're done making your first doll create your own doll thread in this section
Post your 1st doll, and any attempts thereafter. People will post kudos and critiques meant to help you improve. Listen to their critiques and learn from them. No one is ever mean about it, so don't ever look at it as being picked on. We're always trying to help you improve. I look forward to helping you learn to pixel, and will keep an eye out for your Doll thread. Good Luck!
