Wow Ian, you've done it again. My first army was that of the Spartan King Agesilaus and I'm a sucker for rows of bronze hoplons and crested Corinthian helmets. And these lads look like they are all set to loot the cities of Ionia! I agree that the brown armour might be a little dark but the end effect works well. next time why not try the brilliant white linothorax to see how that works.
I am afraid that I am going to be the annoying War-games Fashion Police and point out a problem with your planned use of these figures. The Lambda shield blazon (which you've aced) was the state symbol for Sparta and thus wouldn't be worn by a unit of mercenaries unless serving in a Spartan army. So I suggest that you build a Spartan army that can fight either your Persians or your Macedonians, and then build units of Hoplites with varied shield designs who can serve under any of the three armies. Honest it's a win-win situation, at least for those of us fortunate to watch it unfold!
And those Redcoats are wonderful I do hope that your son appreciates them. The way you turn the bases into battalion sized vignettes really sells me on 6mm as a scale. I've added 5 points to your score for the hand painted shields on the hoplites and the basing on the whole bunch
Ian mentions the 6mm Side Duel, and it's a three way battle between Ian, Tamsin and MarkO with 34 points between them at start of play today.
