This is a Knight from Mardock Keep. He is riding a Bemmoran which is an immensely strong type of warhorse (as you can see by all the chain mail). He is on his way to a war on the border between Serlion and Brandemoore (don't worry about these places, they are countries in Stromguard the continent where Kai lives) I'm pretty pleased with the shading on the chain mail and the horses head too. I think the sword is a bit squiffy and the knight could do with a bit more work (since this picture, I've properly learnt how to draw people in profile - finally!) so I might have a go at redrawing it one day.
