love re-enactment photos and you did an excellent job. the sepia is nice, but the muted colors in the first version are really sweet. i have a cousin who lives on the farm where stonewall jackson lost his arm. butts up against the national battlefield, really cool place to visit.
Some of the other parameters that photographers of Civil War Reenactments have to contend with are:
Modern eyeglasses, in fact I don't remember many images of Civil War soldiers wearing any kind of eyeglasses at all.
The profusion of females in uniform, there were a few (very few) females acting as soldiers, yet in the interest of political correctness we see many females donning the uniforms (usually Union uniforms) in the reenactments.
The beefy well fed look of enlisted men, Civil War soldiers were generally lean and mean - especially those fighting on the Confederate side whose rations were slim to non-existent.
Finally a problem with making authentic images is the evidence of a modern world that sometimes shows up in the backgrounds, these include power lines, cars and modern buildingd as well as visitors to the reenactment...
