It's just sooooooo confusing and it's the best tutorial. I just don't know how to make it.

Yes I do, can you fully explain how you smudged everything? Everytime I smudge it it's completely blurry. And can you also explain how to make the layers "invisible"?

P.S. Sorry for being a newb but I just started Photoshop stuff so I don't know much. Especially the tools and functions.
