Very nice work, the bushes look great.
I'll try to make a beter photo. Sharpshooter is scratchbuild. Beause of similarity of uniform, I've just cutted the bayonet of original infantryman and painted it in green. Saddly I've sprayed to much topcoat so it a little bit shiny

Almost every regt., North or South, had snipers, called sharpshooters in those days. There were companies that would be organized as the such and such rifles at the beginning of the war, but these were not specifically marksmen units.
Is there are any uniform for CSA sharpshooters, or they use standart grey colour?
