Dalinar Kholin Fanart (Stormlight archives)

Tul_

Hey guys, so after recently reading the first chapter of the Stormlight Archives (The way of Kings) which honestly is one of the best fantasy books I've read in a while, I decided to make some fan art of it. In the universe that the book talks about, there's these amazing bulky armors which are incredibly powerful, that worn by only the higher class of society, as it gives the user increased strength and speed and it makes the almost invincible. 

So this is what I've got so far, I'm quite happy about the pose and the 2 characters but I'm not quite sure about the composition. Any ideas or critiques ?
