1/2 Live - did i play this poorly?

[idiom8]

Full ring brick an mortar game. Hero (me) is UTG+1 w/ 88.

Table is good, not too loose, not too tight, varying skill levels. Hero has top stack in this 1/2 NL game with around 700. Next biggest stack is 500, with average stack being around 250-300.

UTG raises to $12, hero calls, a total of 8 players call making the pot $96.

Flop is 6 hearts, 7 spades, 8 of spades, UTG checks, Hero bets $100, everyone folds.

How should i/ could i have played this differently for more value?

all opinions welcomed, thanks
