Technically Ness (The black haired boy) is a silent protagonist but he always felt brave and ready to jump into action judging from the things that happen in the game. Lucas (The Blond one) on the other hand is more timid having experienced traumatic loss in his life, but builds up exceptional courage when he's surrounded by supportive figures. Ness is one of the chosen ones who has to save the world from a cosmic evil, but his compassion for a friend who turned traitorous is what causes Lucas to have to clean up the mess afterward. So it's fun to think about how they would have interacted together. 

A lot of art is really game stylized which isn't my favorite, but I've been hoarding some of my favorite artwork from across the Internet. I know I have a lot more still, but I'll hold off from going too crazy unless someone here wants more of these two.
