This appears to be a tautline hitch, which you might use to tie down a tent, not a mission critical climbing anchor.
I have no clue what this is, with the tension wraps it probably won't fail. The knot is grinding up against the rock and the tree is a joke.
The first knot more closely resembles the backside of a bowline. The second knot is most likely a bowline on a bight, using the eskimo bowline (at least they backed that one up).
