$10/$20 Plays itself or I donked it up?

[Rosslex]

Hi Guys,
Dynamic of the table is that I have been quite active and seen to be LAG. Opponent has been known to try and slow me down.

I sensed I was in trouble on flop as he check called flop pretty quick and lead turn quick too baiting me to push. I thought this was where my LAG image was about to pay dividends though. Either way, could I play it any better / worse?

Should the turn raise major alarm bells? If we KNOW he has a flush on the turn should we fold at this stage or call and fold missed river or just push now as I did?
