Solas is an elf who has lived most of his life as a solitary apostate. He is an expert on the Fade, the world of spirits and dreams. He is polite, reserved, calm, and difficult to antagonize. Years of study and seclusion have made him incredibly intelligent, but also skeptical of the value of most poltiical goals and ideals. As such, he tends to pragmatism rather than idealism. He responds well to people who are intelligent and clever, and thinks less of people who are thuggish and crude.
Note that some of his lines are marked "ancient times", which is when Solas is remembering something profound he experienced in the Fade. These lines are written with a specific cadence. They should NOT be sung or forced into a sing-song voice pattern, but knowing that there is a bit of rhythm there might help the actor.
I did read it somewhere before (I think together with probably the most hilarious description for the bear in JoH xD). But yeah, I think it's a rather apt description, which also includes his preference of pragmatism over ideals.
Which of course reminds me of Inky screaming to Leliana "Now is precisely time for ideals!"
Mostly because I see So... Many... Parallels... between Solas and Leliana I am at this point convinced that they're fully intentional and she was brought specifically to mirror at least a portion of his arc, and clue us in about many details, including potentially could Solas's and Mythals' relationship be like (like one like between Leliana and Justinia).
Like... how does Leliana's arc starts like?
"You know what to do. Make it clean. We were friends once."
.... Which sounds suspiciously to me like a (imperfect, but it's more about the theme) mirroring of the ending of The Masked Empire, where Solas kills Felassan. Thing is, nobody is there to stop him and consider other options. In case of Leliana we have an option to step in. That 'stepping in' in case for Solas for me is when Inky starts gaining his appreciation and trust. Both characters however are still on a route that can turn them into effectively something they hate. I recall some devs calling the hardening of Leliana as effectively turning her into Marjolane - something she feared becoming ever since DAO. There are even similarities between their characters to be made - they're both compassionate and thoughtful, they both want to be inclusive and fair to everyone, but at the very same time they have a darker side to them. They both feel the pull of the Game and intrigue and fostered a cynical/frightfully pragmatic side due to the nature of their role in the world.
Even Solas's description of Leliana on balcony scene sounds suspiciously like his own - 'she has a brilliant mind, but her faith was damaged. For her it's a matter of tactics now.'
And I don't think Solas just means religious faith, but her faith in the world and people. We can even talk about Thedosians with Leliana after they're chosen as candidates for Divine and hear her describe most people as small-minded and petty. Sounds familiar?
Barring some other similarities, the biggest bombshell for me is the description we find of Leliana's personal quest's results we can find in DA Keep:
Inspired: "Reminded of her principles and more certain of her role, Leliana shook off much of her gief and guilt at being the Left Hand of the Divine."
vs.
Steeled: "Certain she was doing the right thing, Leliana put her conscience aside to ensure the greater good was achieved."
Gee! The last one certainly sounds like we could attach it to Certain Someone, at least as of now! 
That's not to say that the mirror is perfect or that they're basically spoiling DA4 to us that way
But I certainly find all those parallels intriguing.
The odd thing is that, before you posted the pic, I was thinking of the cloudy eyes seen in DAO/2 and was confused since neither woman has those kind of eyes. It's odd that they should name those golden eyes that, since that is not how blighted eyes have been represented in the past. o_O
Yes, which is one of reasons I was like... "huh? What the hell?"
Like, maybe someone made a mistake, but I can't really see how two very distinct eye colors could be mixed up. Soooo... it's intentional? But what could this mean? ...Other than we may get some interesting reveals in the next game perhaps?
