A collection of dubious top rope climbing anchors.
That actually looks fine to me. It's a small pic, but that looks like a standard rappel ring, perfectly adequate for a top rope anchor. That tree looks a bit thin, though. I hope it was equalized properly.
On this one, I have to agree with John. Simply, no reason to use the rap ring. Why not just clip carabiner to nylon sling, eliminate the rap ring totally.
