Looks good to me, Dave!
And here I was going to just start with one small single pile; you've really gone whole hog!
I've got lots of big trees that have blown over due to storms/tornado, the roots sticking in the air and big holes where they were once anchored in. Those are the perfect spots to turn into hugelkultur, just start filling them in, eh?
Great article, nice pics, too!
