It's not the biggest image, but it should give you an idea of where it is. You can clearly see the front of a house with what seems like a wall in the background.
I've noticed that before when watching the video. From what I can tell it's a house to the left, a small stone-wall right next to the house, and then a bridge-kind-of-thing in the middle.
Edit: About the dragon fighting...
At 1:48 Dovahkiin slashes the dragon in that direction. The dragon must therefore continue to fly and crash in that direction, which is
away from where Dovahkiin were. Yet, at the final scene, we see Dovahkiin standing right next to the dead dragon.
So yeah, there's obviously a part missing here. We're missing the part where Dovahkiin ran from the place he made the final blow to the place where the dragon crashed.
