NL10 Double barrel bluff hit gutshot broadway on river

[vixticator]

BTN is 52/4/0.7 through 65 hands

I stacked the button for $10+ about 40 hands ago. Flop was a cont bet. Turn K looked like it might scare them away so I fired again obv fold to raise. Figured by the river they had minimum TPTK or hit Two Pair. Good spot to overbet or should I have done something different?
