Those are really nicely done. I've started a unit of Perry plastic spearmen as Spanish myself and I'm really enjoying them - although I'm in two minds as to whether to paint them in a "realistic" colour scheme, or to take a leaf out of Captain Blood's book and paint them in Barcelona's team strip!
You've used the bodies I didn't really consider - I've used the chaps walking myself, along with some metal figures. Yours have turned out really well. I'm looking forward to see what you do with the rest of the box.
