Ahh, but real compound bows do have some metal in them, who's to the black parts are not wood? They may be a bit modern looking for a historical middle ages but has been pointed out, our castle includes the fantasy side as well. They are quite clever in my book, if you are thinking of robin hood and his merry men style forestmen then the compound bows might be a bit big and blocky for stealth, but this group has a more traditional palisade-wall then you'd expect from a Robin Hood style group of forestmen.
I think they're well done and a clever use of pieces.
I also am not going to criticize their factional placement of the compound bows, it's their story to tell even if the story is 'Look at these neat bows we came up with'
It's already more building than I've managed to do recently and likely more clever as well.
Build? I merely Acquire atm.
