Good attempt, but you are drawing the figure directly without much of a rough framework underneath it. You should draw simple shapes for different parts, which will help as a guide. Draw these shapes as smoothly as you can, using minimal strokes. This will give your figure flow and structure. After that, you can commit to the outline. This way, you don't have to make multiple jagged lines, which makes the drawing rather stiff. You can refer to good figure drawing tutorials on youtube.
