I got back to the weapons I was thinking of putting at the top of the wall in the diorama. Here they are:
The club is done, the swords still need work.
So I tried placing them temporarily to decide which one gets hung on the wall:
I like the club, so that's probably what I'll go with. I'll likely have the bigger sword leaning against the wall.
On the heads...the big head at the top isn't working for me, particularly once the weapons go up. So I may end up not using it after all.
