Another recent picture taken on February 6th, 2012 by Fruhtau. Credits go to him/her.

This recent picture confirms that the exterior work is completed. Sadly this and the picture I posted above are the only ones available. This is disappointing compared to last February when a lot of pictures were put up. There should be more since there were two North Korean tours in February. That was what I found out online.
