What do FUE scabs look like? I am not sure whether I nipped out my scabs or the roots. (photos)

I noticed a lot of dark brown dot-like balls which felt like dry skin.Are these scabs?I have attached a picture of DAY 1 and DAY 29.Do my grafts look fine?One more thing,is it possible to see the root once the scab along with the hair shaft has fallen out because I shedded my transplanted hair and I can't see any sort of hole or mark from where they might have detached from my head.Is it normal or did I do something wrong?
