I selected the Layer Style and went to Outer Glow. Set Blend Mode to Multiply, Opacity to 30%, Technique to Precise, Spread to 0% and Size to 24 pixels. Rather than hand-draw the contour from the tutorial, I selected a similar contour, set the Range to 50% and the Jitter to 2:

I went to Pattern Overlay and selected a simple green pattern I threw together for this exercise. I set the scale to 450%:
