My attempt to follow a pattern from a quilting magazine!

I found this pattern several months ago in a quilt magazine. I just had to try it.  Looks a lot harder to do than it really was.  It was a neat pattern to follow.  I usually make up my own stuff but I liked this one so I went for it.  I added strips on each side to make it big enough for  a King size bed. 
What do you think?
