i don't know about "many" mistakes.
preflop seems standard.
turn - you have nothing except backdoor draws, and with so many people, unlike you can take it down. check is fine.
call is a bit light, but your high cards are probably live, and backdoors good.
read-dependent, a raise might take it down on the turn. opponents might put you on very strong because of the previous play. that is pretty tricky, and it seems like you can probably see it for one bet, so a call is not bad.
river gets checked through too easily, just bet it. he'll probably put you on a naked ace, and definitely won't put you on the flush. you may get raised.
