Party 600 w/ AA Turn play

[Twentysack]

Villian is semi loose but not total donk, so far im probably viewed as aggressive. Villian is capable of calling my opening with a big pp. After the flop i think hes on a pocket pair (44 is a possibilty) A hand with a 2 is unlikely unless its A2s (But i do have the Ah). Mainly want to focus on turn play and was the C/R the best move?
