But in the end it came out well I think. The wooden floorboard resin base from Tiny Worlds Wargaming came out really nicely and shows off the model to great effect. I can't recommend those bases enough!
Now the Barrels were much easier. I started with a base coat of US Field Drab from Vallejo Model Color (70873) on the wooden parts and Lufftwaffe Uniform (70816) on the hoops. The wood got a wash of Agrax Earthshade to pull out the details and the hoops got a Nuln Oil wash.
Thats as far as i've got though. The plan is to finish off with a Grey Blue (70943) highlight on the hoops and to glue them all to a base so they can be used for lots of different games.
I'll put up some photos of the finished work soon.
