He is definitely not happy with how his men are performing drill.
When I first pulled this figure out it took me about 3 seconds to decide on a vignatte when it is mounted with his element for Victory Without Quarter. This sergeant will be leading a charge with a block of pikemen.
The drummer will be part of Talbot's Yellow coats. There is not a lot of evidence for the uniforms of musicians in the ECW so I am taking some creative license with this figure.
I am researching the existing known drums, illustrations and descriptions before I tackle painting the drum. One source I have found useful are the websites of reenactment units of the English Civil War Society and the Sealed Knot.
I still have not decided how to paint the ensign that came with the pack. Once I decide on a regiment and flag he will join the production line.
