Well, here are the results after a week or so of mucking about with the 'wet palette' and a reasonably small batch of figures.
The painting is certainly not earth-shattering, but I probably do pay a little more attention to detail in doing a smaller batch, so it's an approach that's perhaps worth pursuing.
These still have a little bit more to be done on them, but are pretty much done. Only another 150 Gauls to go...
Onward and upwards!
