Massive dragon battles and giant dungeons are cool and all, but what were the little details you spotted in today's footage?

All times according to this video-

2:43- Pendulum traps can be see in the hallway behind the draugrs.

3:15- Talk prompt for Giants? I wonder what they sound like.

3:19- Does anyone else thing the tree in the middle-left of the screen looks really weird?

5:20- The frost dragon is just named "Dragon." It's interesting considering the Draugrs and bandits all had different titles.

5:38- The dragon hitting the ground visibly scars the land. It's still there at 5:53.

What did you guys notice?
