Thanks for the chapter!!! The Council is broken up into 3 groups. The Elders, The Civilian, and The Shinobi. The Shinobi council is shown in canon as the major clan heads. But realistically, would be broken up into all clan heads big and small, Department heads, and other miscellaneous personnel that wouldn't fall under those 2 main headings. There is a large support staff to run a village.
I actually think the council would be larger than even you displayed. the original cannon anime i always thought was a large verse that was made small for a child's entertainment. I believe every decent sized clan would probably have a seat including things like a big civilian farming clan head and a few merchant clan heads. I'm sure someone focused in construction would also have a seat.
