nice set 
What about building a road to Kish so we can get some more trade routes.
Libraries are really needed, especially in Uruk.
We can run some scientists there to boost our research.
Normally I would go for alphabet to trade it for fishing/iron working, but we have only 2trade partners now. The warrior east of Shaka should do some more scouting to find trade partners, and the vulture will be ready in time to defend against the barb archer.
We should set 1 warrior west of our cities to fogbust. I just see there is only 1 hill where barbs can spawn 
I think we should release shaka, but make sure that he doesn't get horse (or copper/iron), just set the vulture on it. That way he won't get anything stronger than archers, but he will get more cities wich we can steal later.
