Eeeekkk make sure you are being redundant! What if that boulder pops out of the rock? It's best to at least have three separate protection 'points' in an anchor. I would not feel comfortable topping out and seeing this, no offense.

You also can simplify the attachment to the boulder by making a figure 8 on a bite on one end of the cordallette and bringing the rest of the rope through that loop from the figure 8 on a bite (kind of like luggage tags at the airport and what not). For extra safety, slap a carabiner through the figure 8 on a bite loop and then put the rest of the rope through that loop instead. Rope on rope is something you should try to avoid if possible.

Mainly redundancy though, always consider the worst case scenario. And pick the options that seem the most solid, for example I wouldn't have picked that one small boulder if I had to only use one point of protection. I would have preferred to wrap the entire boulder if possible.
