I finished the story quest for Western Skyrim and although I enjoyed it, I'm a bit sad that Svana didn't get a proper ascension with regal clothes etc.
So here's my imagination of what she might look like as the High Queen (very crudely - I am not good at drawing)



(I realize she may just have inherited the clothes from her father, but I have a steadfast rule that the betrayed don't wear the ropes of the betrayer, if you get what I mean)
