I think it looks really cool :)

Works for me, very pretty.

I think it turned out more than OK!! Guess you showed that instructor a thing or two!! haha!! (you go girl!)

It's very cheery! I love it!

oh, i soooooo want that! it's gorgeous! :)

Turned out fabulous.. Now every time you look at fabric you see Stack and Whack don't ya??? Great pattern..

LOL, Ain't that the way of it?

SEE???
Instructors don't know everything!
Good for you!
To be fair, none of us alone can know everything, and we do tend to our preferences - - it is a human condition.
But, I think your quilt is just dandy, and the look is unique.
As I used to tell my children - - try it once, if you never do it again, you will know why (I did have the caviat that it must be logical, ethical, and moral, or the first time really isn't necessary <g>)
At any rate, I am glad that you followed your first choice in fabric and broadened the stack and whack horizons <wave>

Awesome one of my favorites to make

How pretty!!
