Did I play this poorly?

Would I have been better served leading out? I am OOP. Villian is reletively unknown.

Any way that I would've been better served? Comments and criticisms welcomed.

Note: I don't normally play AK this way oop, but I was fairly confident I had the best hand on the turn. Unfortunately I recieved info that I may have been beaten on the turn and still called down.
