Paint By Numbers?

So, the walls in my living room are mostly blank and boring and I've been unsure about how to fill the wall.  Shelving?  Barrister's bookcase?  Artwork?  The one wall that bothers me the most is pretty huge....the ceilings are about 16 feet tall (don't quote me on that).  The only thing on the wall is an entertainment console and the TV.

My current view of said wall, as I sit on the sectional and blog.

Bor-ring, no?  Keep in mind that wall stretches another many, many feet above where the photo ends... we're talking a lot of grey.

I've thought it would be cool to have some sort of artwork hanging to the left of the TV... something soft, maybe a tapestry of some sort.  But, like I said, I have been paralyzed and haven't run across just the right thing.  Story of a perfectionist's life.

But...

While at Home Depot today browsing the spray paint, I noticed their canvas drop cloths.  There was one that was five foot square with hemmed edges for less than $8.  I picked it up, thinking maybe I could create something for that wall out of the canvas.  

I got home, hopped on Facebook and asked my creative sister-in-law to help me brainstorm ideas on what to do with the canvas.  She pointed me to this post from Layla, a blogger from Birmingham.  Paint by numbers?  Really.  Oh yes.  I am sold.

So, I've been browsing Ebay and Joann's for paint by number kits... Joann's was basically a waste.  Ebay was far more entertaining.  Turns out there is a surprising amount of dirty paint by number kits.  And a not-so-surprising amount of tacky paint by number kits.  Anyhow, I would love to hear some input on a few I am considering, so give me your thoughts in the comments, please!

Let's start with my favorite piece  ::

Kidding.  Clearly.

This one is actually my favorite  ::

Okay, for real.   Option 1  ::

Option 2  ::

Option 3  ::

Option 4  ::

Option 5  ::

I like that the method on Layla's blog allows for customization of colors, so each of these PBN projects could look very different (soft and neutral, edgy and bright, etc.) based on my own color choices. Also, I am not sold on any of these, so if I find more options, I'll post them here for more feedback.  Okay!  Thoughts!  Let's have 'em!
