I love Hordes; I need to get my 15mm fantasy armies dusted off and convince some of the other local games that HoTT is not, in fact, "too simple"...
I also have more 15mm Dwarves than I will ever be able to paint (many of them the OOP and missed Ral Partha AD&D Battlesystem figures) so while I like your daughter's all-female army, I also highly approve of your son's choice of combatants! I really like the banner of the Dwarven general, especially.
