Thanks all

@Rick F - the whole post-Roman/Arthurian period always feels like it suits a slightly faded, barren feel. It's a world leaving past glories behind, in transition to something else.
@ulverston - Victrix make very nice plastic kits. They don't quite have the character of the Footsore metal Romano-British, but the versatility and price point of the plastic is definitely a win.
@olivero - the designs on the shields are Little Big Men Studios shield transfers. They have a full range designed for Victrix sculpts, available on the Victrix website. The wood grain is just one of the Vallejo Xpress colour browns over wight bone primer - they're already nicely detailed wood shields.
