To the Window to the Wall

We're talking wallpaper today, friends!  Come on now, what was your guess with a post title like that??

Large scale wallpapers are HUGELY popular now (ha ha).  Long ago are the wallpapers of the 80s with dainty little pastel flowers...may they rest in renovated peace.  I'm suddenly feeling the design urge to go the wallpaper "look" route on an accent wall in my entryway/foyer.  I'm crazy, I know, but these rooms below are just so inspiring.  They make me want to jump on the crazy train!

So, after that visual circus, you may ask what space I'm working with and what direction I'm going with this wallpaper "look" notion.  Here's the entry - the wall to the left is my target wall (the wall the door is on).

Now here's the catch...with the house being a rental and me being noncommittal when it comes to more-permanent decor options, I wouldn't actually wallpaper the accent wall.  I'd make a stencil that would look like a large print wallpaper, and then paint the design on.

Here's the large scale wallpaper design that's giving me inspiration right now for a stencil job:

What do you think?  It's sort of a sunshine shape in relief.  Not sure what color I'd do - chalkboard black would be nice and graphic.  Dark gray would be more subdued like above.  Navy blue would match the powder bath situated across from that wall.  What would be your recommendation for the color?

So, should I give it a whirl, friends?  Come on, I need your advice!
