First off, gorgeous paint jobs. Just wonderful. Now the critique of the sculpt:
1. British generals only wore one epaulet on the right shoulder. One.
2. I believe only flank company officers, and I want to say Highland officers, wore two epaulets.
3. Hair in the British army was generally clubbed, not braided. Grenadiers wore their hair platted so they could hook it into their grenadier caps.
4. General officers did not wear their skirts turned back. The pattern of a general's coat – both dress (which was embroidered, not with lace) and undress (no embroidery) was very distinct. They had a short standing collar, and small blue tab that went over the front edge of the collar. The buttons were spaced according to rank – two for major generals and three for Lieutenant Generals. Same for lace pattern on the sleeves and sides (below the pocket area – but with no pockets) of the coat. The inside lining of the coat was white shalloon wool. The cuffs were very small, more like cavalry cuffs – in an inverted V shape. The buttons on the cuffs also reflected the rank (two or three buttons).
5. It would be more common for the American officers to wear their hair clubbed as well.
Again, excellent paint job, nicely done. I'd be proud to have them in my army.
