The unique advantage of a vector editor is that all strokes remain independent objects. This makes it easy to nudge, scale, or rotate parts of your drawing. With the Selector tool, drag around the leg or the head to select all its objects and use either the mouse handles or the convenient keyboard shortcuts:

Usually, with every such transition your drawing will look less and less like a pencil sketch and more like a real ink drawing with smoother strokes and more elaborate details. Here is my third inking attempt over the previous sketch layers (the head was especially difficult to sculpt—my horse originally looked more like a hippopotamus):
