I'll do what I can to help ya but I don't have the tutorial on my new computer (old one broke) and haven't yet downloaded it from the guild (I'm piecing together the rest of my life before I get my art stuff put back together). So it looks like you got the gradient overlay working, good. The blue is a different layer style called outer glow. To get to that you have to do something like click the ok button to complete the gradient overlay process. Then go back and click on the little cursive f in the bottom of the layer stack to bring the layer style dialog box back up and then click on outer glow. Then follow the steps and you should be ok. The layer for the gradient and the glow is the "land" layer.
