I just painted up the shields for my first couple of Early Imperial Romans. I went off of the shield design that is on the http://www.miniatures.de/toe-roman-cohors-quingenaria-equitata.html website. There was no way my eyes or hands could handle anything quite so detailed. So I tried to suggest at it. Not sure if it worked or not.
Here is the six that I have finished up. I have most of the command element for my first century. The Optio, the Signifer and the Cornicen. Also I have the guy who will be the Tribune for my citizen cohort. He has a pair of servants to take orders and hold his shield (apparently).
Next up is figuring out the basing. I believe that I want to have square bases for my Romans to allow them to be placed close together in formation. My Germans (whenever I get around to them) will be on Round bases as they will not be able to do close order formations like the Romans. Well, that is the current plan. Stay tuned. It could change. Anyway, things are at least progressing.
