Iron Man On Set Avengers 2 Pic

The last few days we’ve seen an influx of pics from  the set of The Avengers: Age Of Ultron and now another few have turned up. This time featuring Iron Man and a better shot of whats believed to be Ultron (although some believe its a drone). Whatever about Ultron (or Ultron Drone) , I wonder is the Iron Man suit not a finished product. It looks a bit plastic to me, and maybe its been used for lighting references. I’m not sure. Anyway, the pics are below and again let us know if you think these kinds of images spoil the movie. I’m always stuck in a dilemma posting these!
