The only way to counter that image the you cultivated early on is to tighten up and make the next hand you showdown a premium holding. As for the two hands I don't think you are out of line betting the turn in the first hand, even with your image. In the second hand even though everyone thinks you are a maniac I don't a player is going to pound you that badly on the flop and then lead out the turn with anything you beat. I would have just called down on the turn if for no other reason than to show the table you were betting TPTK.
