As is normal for me, I based all the figures and spray undercoated them white.
I had the idea that I would use my airbrush to do the tunics. Then in another moment of slight stupidity I reckoned I would apply a black wash in the same way. Initially, the result wasn't that great and I think I should have used a brush for the wash.
Here's the example. The figures on the right have the airbrushed red and black wash. A bit dark for my taste, but once they were tidied up with a bit more red on the tunics and grey on the straps they looked better. The chaps on the left have been tidied up.
And a highland unit.
The first 4 battalions. The front 2 the units are just undercoated and washed with black. I think this is a better way to do it, black wash first and then the red.
I also decided to leave the horses as undercoated white. I can do a batter paint job on them over white.
By the time I was looking at the heavy cavalry figures I had decided to do a thinned black wash by brush as I could get better control of the paint flow. Here's the Scots Greys, some with the just the black and the others with red tunics. Not a bad start.
And a bit more on the Greys and one heavy dragoon unit. It's starting to look reasonable.
I'll post more as I get the chance. I'm planning to do 2 or 4 infantry units and a couple of cavalry units to start with. Then I'll assess how best to proceed with the rest. There's a total on 10 infantry battalions, 5 cavalry units and 2 gun batteries as well as several generals.
