burning the clouds layers down doesn't appear to be working...

I still cannot get this to work in PS (CS3).... delgondahntelius' method doesn't seem to give the desired results. I've tried numerous variations of the methods described here and still I don't get a good looking coastline.

Anyone that knows how to do this in PS and can give a very step-by-step description of exactly how they do it? I'd really appreciate it.
