6/12 B&M Hand

I rarely play limit and have never posted a limit hand before so here goes:
Hero is dealt 7d 7s
Canterbury 6/12
Folds to CO
CO Raises to 12
Hero on Button Re-Raises to 18
SB Calls, BB folds
CO Re-raises to 24
Hero calls, SB calls
Flop Jc Jd 2s
SB checks, CO bets, Hero raises
SB calls, CO calls
Turn Qd
SB checks, CO bets, Hero checks
River 7h
SB bets, CO calls, Hero raises, SB calls, CO calls


I'm not a great limit player so I was hoping to get some help on this hand. Any advice is appreciated.
