From what I recall, that's a soldier of a "flank" company, and the epaulettes would need to be smaller for a soldier from the rest of the Battalion. It's a long time since I did any reading on the subject (Sean Bean as "Sharpe"--excuse me whele I de-drool my keyboard), but apart from that option it looks pretty good. I wonder if the tails of the tunic are a little over-simplified.
