Entryway Update - Ain't Gonna Happen

Ok, so I had hoped to create a look of wallpaper, without the "wallpaper" something like this,

and here is how I attempted to go about it,

using painters tape, 

I ended up with trees

Then after all this taping, I was going to paint over it all  with a lighter color, then pull off the tape and voila, a master piece, but instead  I decided, I hated it.  So now back to the drawing board.
