NL 10 - TT on the button, OESD+Overpair underplayed ?

[Seeeno]

I feel like I underplayed the hand.

The Preflop call should be again AFAIK.
but I def. should raise this flop.
I was blinded by the fact I got odds to draw to my oesd, but my overpair+oesd is worth a raise here.
as played this would be a good spot to rep. the ace in combination with a value/ semibluff/ freeshowdown bet.
Checking behind this Turn is criminal ...
