Hands and feet suck

For some reason, I can draw pretty decent big pictures of hands, like when they're not attached to a person or anything and you're just drawing..hand. But when I have to draw them in positions and make them smaller they look like a rat drew them, I don't understand. Feet just suck, I have to redraw them at least a hundred times before it looks decent enough to be in the picture. Anyone who can easily draw hands and feet in one go and not have to constantly redo them, you have my respect.
