Failed compost pile

I constructed this pile last spring.  It was a perfect mix of carbon to nitrogen.  It had 12 ingredients, including seaweed that I painstakingly collected, expensive biochar, and weed tea.  It went through a really hot summer, and though I thought I shielded it well (I didn't), it was dry most of the time.  Here are the results.  No noticeable decomposition.

I'm so bummed.  I need to watch Dr. Elaine Ingham's compost videos.  Here's one.
