The trick to creating paths is click, then click + drag. When you click and drag it creates a bezier curve which is smooth. You can probably take what you have and tweak it. Try using the convert anchor point tool (I think that's it). It's the tool that looks like a black "V", but rotated around. It's likely found under the white arrow tool with a long click. Click the points on your path and drag. They should become curves. Use that and a combination with the white arrow tool and you can make a much smoother shape.
