you didn't have plans for the potsizes your bets were creating

you should have reraised more pre, and you should never make this bet on the turn without a clear plan for the outcomes. to bet 16 and fold getting 5:1 is horrible so you should call. but perhaps you should have c/rai or even c/f. bottom line is you created an unprofitable situation on the turn that could have been avoided by shrewder play preflop and on the flop.
