A very nice figure.
You've recreated a Greek(?) soldier very well, one thing I'd really like to see in this picture is more of a background. The soldier is there but you've got to give him a position, the background and surroundings really change the mood of the picture, so it's always an improvement if there's a bit more detail in the background.
Otherwise excellent figure, and according to my relatively small knowledge of ancient history, it's an accurate drawing. I don't understand why he has a shield but no sword? I cannot even see one sheathed.
There is already one reason to add a background! :D
