This might be the only fanart of Danarius in existence, hoboy.
Wow, they really made her look like she could be Fenris's sister, despite the hair color, even more so than the game version. A+!
Yeah, I thought they found a nice balance! I wonder who was in charge of her design... I just assume she and Fenris had different fathers or something.
To your previous remark about brunettes... I'm in that camp also, and was thrilled to have a fave swarthy LI in DAI with Dorian. Generally, the character themselves influences my perception of their appearance over time as I get to know them. I'd certainly attempt to go for Mae if she were available as a romance option. Lol... I can just imagine myself having one of the first conversations with her after recruitment, seeing the
icon, and hitting that so hard I practically break my mouse. 

Same. "Pleeease don't pull a Vivienne/Varric/Harding/other person I can flirt shamelessly with but not actually smooch."
I can't begrudge anyone their blondes, since we've had so very many brunette LIs (at least as far as women go. Far more male LIs with light hair!).
The only concern I'd have is the likelihood that they would write a character like that as a chilly ice queen (she looks a bit like a chilly ice queen, to be fair), and we've got that type pretty thoroughly covered in DA. I'd prefer the calculating but affable type.
I like the idea of a playful but mature personality. A bit like Leliana if she'd been raised in an elitist magocracy, lol.
