It's a good idea to comment a game

!
I just look the first two move but i have already some advice :
1st take i would have done the same, always a must to notice which card you give (mountain more than other card, so f2/f3.. and the tresor card with bureaucrat. I dont find matriarch good).
2nd take... well C6 because you get a carrot and a fish adjacent (its always a good territory, even more because you got the pearl). But not G2 (too far from a fish to rentabilize your pearl, i would have taken the master of the Mountain or camp.
In term of strat at the start i always prefer objective than a lone territory to get more flexibility. You never know what your opponent will take. If you choose your "localisation" too soon it will limit your choice later.
Generaly, I only take territory if i have no choice or if i got both adjacent. And if i have no choice, i always focus on mountain or at proximity of a mountain (they can get a 3 castle and 4 type of ressource).
This are few advice only for the very beggining (i could write more but i'm a lazy bunny to be honnest

), after that it depend only on your very first choice
