Well done for catching yourself before starting on a second stone and then carrying through with the social media.
I was intrigued by your scoring of the project and wondered what it would take for you to give yourself an A or A+ for the creativity part? For me I think it mostly comes down to the feeling.
I would rate myself a B for the creativity because I haven't had as much playful fun as I'd like and, at least to me, there hasn't been much variety.
As for the recording that would be an A. Simply becuase I've done a post every day and posted on Instagram.
