Entryway help!

So I just moved into my condo about a year and 4 months ago. When we first moved in the walls throughout the condo where an ugly beige color. It almost had a pink tint to it and really had to go. I started looking around at paint colors and decided I wanted my entryway and living room to be one color so it flowed better. After looking at many colors I decided I wanted a greyish color of some sort. Not totally grey (because it may get depressing) but maybe grey with more blue in it. So I chose Benjamin Moore's Pewter 2121-30.

Now although I like my idea of the color of the entryway and living room matching so it creates a flow like feel, I think the entryway needs some sort of umph if you know what I mean. I was thinking of maybe adding a stenciling of some sort to the entryway and through the hallway in white or silver. That way I don't have to go through the painstaking wallpaper routine and if I get sick of it I can paint over it. I found some really great stencil designs and want everyones opinion on which one to choose. These are a few I was looking at:

{Fuji Allover Stencil; Cutting Edge Stencils}

{Zagora Allover Stencil; Cutting Edge Stencils}

{Casablanca Allover Stencil; Cutting Edge Stencils}

{Rabat Allover Stencil; Cutting Edge Stencils}

{Quatrefoil Venetian Tile Pattern; Designer Stencils}

Any suggestions?
