Those look pretty good. Is Darrian your "canon" Warden, or will you be importing all of them into DA:I at some point? What's your canon Warden like, if you have one? Well, aside from hating humans if it's Darrian... xD Good, evil, neutral?
Actually, my canon Warden was my dwarf noble, tbh. He was cocky, friendly, a fairly decent tactician, pretty indifferent on humans and elves, and pretty loyal to Orzammar. He was pragmatic to a point, believing that sometimes going with what you feel is right is better than choosing the 'logical' choice. I suppose he was more along the lines of Neutral Good? Seems appropriate, imo.
As for Darrian, he was more along the lines of Chaotic Neutral. He valued his fellow elves above anyone else, to the point that he would be more than willing to die to protect them. He's not very friendly towards humans (obviously), he rejects the Chantry, and he comes off as cold and ruthless, but that is mostly due to his anger towards humans (picture him like Fenris, only angrier and his anger being focused on humans instead of mages). Under all that anger, however, he's really caring and fiercely loyal, though it takes a lot for that to show. He is quick to anger around humans, especially when fellow elves are threatened, and he's utterly ruthless to his enemies. I like to headcanon that learning that the Tevinter mages were kidnapping elves to make them into slave sent him over the edge and he went on a murderous rampage, killing any Tevinter in sight. He also executed Loghain personally, for obvious reasons. He had come to trust Alistair by the time of the Landsmeet, so he supported him for the throne, basically telling Anora to take a hike. Despite his distrust for Morrigan, he did the DR because he wasn't about to die to save a world where his people were treated as second-class citizens, not to mention that he didn't want Alistair to end up killing the archdemon, which would end up with Anora on the throne. I headcanon that he stayed as Teyrn of the Denerim alienage in the years after the Blight, helping to improve the living conditions there and putting forward movements to improve living conditions in all Fereldan alienages, despite what the other nobles thought about it.
... yeah, I kind of went overboard with my description for Darrian. He is my favorite Warden, so I tend to be more descriptive of him than my other Wardens... 
Oh, neither of them romanced anyone. Didn't romance anyone with my DN because the height difference took the seriousness away from whatever romance I could've done and I didn't romance anyone with Darrian because 2 of the 3 LIs for a male Warden were human (couldn't see him getting along with Morrigan or Leliana enough to develop a relationship with them) and he was straight, so no to Zevran. I could headcanon that Darrian eventually bumped into Merrill and they sort of ended up together, but it probably wouldn't work because I romanced Merrill when I imported Darrian into DA2, so...
Hmm... not sure who else I could headcanon him ending up with, tbh. Meh, I'll work on it later. Not like I need to have him end up with anyone, anyway. 
Oh, also, I plan on importing all my playthroughs into DA:I.
