That concept art shows like 5% of Riften and a random interior... how the hell could you compare the finished city with this...?
You must be really bored that you made this thread.
No, this is stuff I like to do. No different from any other thread here. This might not show the entirity of the concept city, but it shows just as much of the city as is in the final version. They look completely different in the parts we can see. If you don't see how they are different they are, I could easily create a long list presenting noticeable differences to explain it to you.
