I just finished my first 15mm miniatures for my Carthaginian army. I painted up all the mounted units first, excluding elephants, and then will be moving to Spearmen next. I have never painted 15mm before these and I was struggling with finding a balance with the level of detail to paint vs what will actually be seen. I am very happy with the end result and feel like I found that balance.
First was my mounted general stand.
Next a stand of Carthaginian cavalry.
Last is 4 stands of Numidian light horse. For DBA I only need 2 stands to cover all the options but had accidentally ordered double so just painted them all up.
