A couple of suggestions for tweaks.
Trait: "Highland Ingenuity" Worked hill tiles provide +1 food and +20% combat strength for units on hills. (as you had before) Generally set up to make settling in hilly areas more appealing than other civs would find.)
Unit: "Citizen Scout" Replaces the normal scout. Half cost, -1 strength. Encourages quick early exploration, but at the cost of being even weaker than the normal scout.
Building: I feel that your Clan Castle is an excellent UB and wouldn't change it a bit.
