Finn! My favourite elphin guy! He's rough, he's tough, he fights for any reason, or none at all. He has two (two!) mechanical arms, which he can put on all by himself, that's how awesome this guy is. And I think it shows in this portrait. He looks grumpy, but there also is a hint of 'don't get to close, don't break down my walls' about it, which gives him, in my eyes anyway, a softer and more vulnerable side that I am going to explore in future stories.
The greatest thing about this portrait, apart from being a complete surprise, is that he is so well portrayed that it will help other writers to get to the core of this NPC.
I love how alien he looks. He's a mix between an alligator and a fish, and that's awesomely done.
