The top shot is the new development the little fat kid ordered when he came to power. I'd guess the photo is taken from the base of the Juche tower. You wouldn't have seen any of it if you came before ~2011/2012.
The last one is the Mansudea Assembly Hall, which I did manage to get inside once (

Sorry to hijack this thread with my own picture, but I might have a slightly better perspective of that tower. Never been in, but I've been on the site before they restarted construction (try asking about it when you visit the textile factory thing).
