I've started a potential final illustration. I thought for full impact I'd have a big battle scene so the plan is to have smaller units crawling around all over the place. I got a little stuck in detailing the focus of the piece though so there's not much sense of scale yet however that shouldn't be too hard to fix.
One very useful thing about getting some more detailed lighting in on the focus is that I can make sure the background elements give as much (or as little) contrast as I want
C&Cs are veeeery welcome as I'm alwasy fearful of sinking too much time into things like this
