I tried. Not 100% acurate, but I say a close 90% I don't know if I can get him to look more like his past self, since cheekbones were so exaggerated in origns
Blake Amell - Dragon Age Origins


(Maker.. How I hate the hair and the stubble in inquisition's CC ¬¬ Since the stubble options are all bad, i had him shaved .-. But considering what I had, this is the closest I can get.)
He was generally a "goddie" warden, aways ready to help those in need but had a secret lust for power, witch lead him to make a deal with the desire demon that possessed Connor, to learn blood magic. He used this powers for the fight aganist the blight, but now regrets this choice, because he later learned that Connor became possessed again and was killed by the templars. He also made the Dark ritual with Morrigan - even if he didn't like girls but hey, anything to survive right? - He did it knowing that someday this would bite him back (but ultimately didn't, I'm so disappointed with this story arc ¬¬), and was ready to face the consequences. He had a romance with Alister and remained his secret lover after he became the lone king of Ferelden. A shame I lost this because of the Keep, it was really amusing seeing it imported to DA2. He slayed the aquitect, because he simply couldn't trust a darkspawn, even if this one seemed rational.
