Looks good to me.
Some things to think about re 3 betting vs flatting.
What would 3 betting TT achieve vs a nit with a tight opening range and tight 3-bet continuing range? Can you do this, for value, as a bluff? What are you doing vs a shove and is this the most +EV situation you can create preflop?
The flop is a pretty easy fold vs a guy whos range is just tight as shit. Your equity sucks to improve and you're behind or going to be folding by the turn too much to ever continue here.
