In order to get motion blur to work you must have motion.
As you did not mention using Mover I suppose that it not was imported as an animation but rader imported as a posed model and if so there is no motion unless you did something like setting up a keyframe, move the horse and the rider and set a second keyframe, then move the timeline somewere between the keys and do a render with motion blur. It would of course not be a totally correct blur as the legs of the horse not moves in a straight direction between the keyframes but maybe better than nothing.

If you used Mover an actually imported an animation then check that the kind of render you did also renders motionblur. I kant check now but as an example I'm not shure doing a Final render is enough.

I really like the models in the picture except for that I would like to se more structure and dirt on the skeleton and the shield.

What I dont like at all is the lighting, the image is washed out, try to start by turning down or totally turn of ambient light and just add the lights you need. It would move more of the focus from the very basic and uninteresting background towards your main characters.

You could also try using HDRI (unless you allready did, but if so turn down exposure).

Just my 5 cent's based on my own taste.
