2 pair faces aggression...how's my line?

No reads on villian as he is new to the table. I have been playing pretty tight, only showing down big hands. I hate the size of my turn donk bet...I didn't want to lose everyone blah, blah, blah...it was bad, I know. As played, how is my line on the rest of the turn and river. All commeents appreciated. Happy holidays to all.
