Pretty certain that the concept is from the Fjord Rafting side of Scandinavia, just mirrored for some reason. You can see that the building on the far left of the concept is the same building seen in this photo, only now the back of it will be red rather than yellow:
The facades facing Fjord Rafting in that concept are certainly more different than I was expecting them to be. The profiling of the buildings is pretty much the same however the styling has changed, parts of it seem a little less authentic and more whimsical. The Vineta building for example seems far more detailed!
I can't make my mind up yet as to whether or not I like the changes. I am however looking forward to seeing the finished product.
