The start of a Roman WAB army?

This one's been in a semi painted state for a few months now, but I dug him out and finished him off today. I have a bunch of these Foundry sculpts and their Dacian adversaries, but they always seem to be on the 'to do' list.

Although they should be easy enough to paint in large batches because the colour schemes are quite basic (... by that reasoning so should the ACW...), the major problem is the shield. As this was a test piece to see whether I was inspired enough to do an army, I did this one totally freehand. The prospect of doing a hundred more is, however, enough sap my will to live. Although it looks ok, I will order some decals and paint over the top of them. Decals never look quite right on their own, but as a template they'll be fine.

It's a shame I painted this model and then attached the shield. I didn't realise the torso would be completely hidden until I attached it. I guess that would save quite a lot of painting time too ;)
Having looked at the tunic colour debate that seems to get the reenactors so animated, I was swayed by the 'undyed' option as for Trajan's army on campaign, resupply would be an issue. Just a shame you can't see it!
