Nice job PP! I was actually using your image to try to scale mine as well, so I'm glad you posted.
I am now guessing the object to the east is a wing with a substantial piece of fusilage, and the object to the south is the other wing. Engines, APU, landing gear must be in the field above the southern wing-like object. There are two other symmetrical objects in that field.
I believe you noted previously the A330 wingspan is 60.3m.
I have yet to see any photo with a rock in it, so I am guessing all of the returns are debris. The recovery team "lucked out" in a sense (seems like a terrible thing to say...), because I'm sure this would be much more difficult in rocky undersea terrain.
