In Need of Feedback on Medieval Weapons

Bazihar

Hey, i'm doing a study project of an katana and a buckler shield with this kinda of "cheap material" base style, like, both base pieces would be considered low quality pieces with this almost like parasite wooden branches that starts to spread along it, there's still some word to do on the blades of the katana and wooden planks on the shield but what i'm really looking for is feedback on the wooden branches, the ones in the katana we're done way before the ones in the shield so i need  to comeback to it later

Those are my main refs for the branches
