Thanks a lot!
Damn they are all pretty good looking. 
I am going to need a paint tutorially for your Union troops and Confederate officers.
Alright - for my Union coats I start with a Night Lords Blue base, followed by a wash of 50/50 Corvus Black and water, followed by watered down Abbadon Black wash in creases etc. I then do a really subtle highlight of Macragge blue. Then a light and subtle drybrush of Zandri Dust on the skirts and elbows.
For the CSA officers I either do a basecoat of Russ Grey, followed by a wash of 50/50 Skavenblight Dinge (or Rhinox Hide) and water, followed by a highlight of Fenrisian Grey and subtle Zandry Dust drybrush on shirts and/or elbows or a basecoat of Dawnstone, followed by a wash of 50/50 Skavenblight Dinge (or Rhinox Hide) and water, followed by a highlight of Administratum Gray and subtle Zandry Dust drybrush on shirts and/or elbows.
Hope this helps!
