First of all, excellent tutorial. You have a very clear spoken voice. I am getting a little stuck though. I am not sure if it is my cs 3 version, or what but I have 2 main issues. First, in step 15 when I select color range it comes up as empty. I imagine that is because the layer is only a clouds layer with a layer style color overlay. So instead I used magic wand and selected anything that was black. However since this is a common step in the rest of the tutorial, I wonder if there is someway to fix this.

Second issue is in step 26 If I clear layer styles on the ocean adjust layer, it reverts back to just a black and white clouds layer. The layer style on it is the color?

Because you didn't indicate the reason for each step, I don't really know the goal. Are you trying to have 2-3 different widths for shading and height?

Thanks again for the tutorial and for any help you might be able to offer.
