Verrry nice, ditto detail on the shield backs.
Auxillia are on my shopping list, and I'll be replacing the plastic spears. I just completed a half century of thier EIR and managed to break a couple of pila (admittedly thinner than those spears ) ranking them up - sausage fingers dont help, but over time...
For the Gauls (British opponents) I went with the Warlord steel spears
here cut down for for javelins, and the slightly thicker North Star ones,
here, for spears. Both are 50mm long and work well with 28's. Only thing you might not like is the very industrialised uniform spear points everyone ends up with.
