I like Charles' face - very good likeness to portraits of him, but he seems a bit too "active" to me. I've always imagined him sitting serenely whilst everyone else is rushing around. Great figure though and very tempting.
Montrose is slightly disappointing. Not the sculpting of himnself, which looks very good indeed, but he is a little "generic". Really, he could be anyof a colonel of a horse regiment. His horse isn't the best I've seen nut theta may just be the angle of the photo.
I'd buy Charlie, but maybe not Monty
