The fellow with the exposed face looks as though he was added later, but other than that, it good.

The Blue Knight is the most detailed. The others though, they are high detail, but I have this feeling that you wanted us to focus on the blue knight more than the others.
The one guy who's face is exposed, seems to lack just a bit of detail, in terms of realistic effect in the face. Also his sword has a Dim feel to it, when looking at the relecting tone of the blue knight.
lastly, the guy with the brown cape, could use just a some more shades of dark brown to cast that stressed look further.
Other than those points listed, this work is phenomenal. I hope I wasn't too harsh. I only took .5 off due to the shaders, but this is definitley a 9/10 job. keep up the good work.
