how badly did i botch this hand?

[bigjoet]

first time in 40/80 at commerce... confident and running good in about 2-3 orbits at the table... game is currently 6 handed with several walkers.. no reads on anybody yet...

preflop:
all fold to CO who raises, button 3 bets, sb folds, hero sees red AA and 4 bets, CO & button call

pot: 12.5 sb

flop: 8h 4h 2s
hero bets, CO/button call

pot: 15.5 sb

turn: Qh
hero bets, CO raises, button calls, hero insta-3, CO hates it and calls, button 4 bones, hero calls, CO thinks forever and folds...

pot: 18bb

river: random blank
hero c/c

i'm taking a shot at the 40, and i'm not used to ppl trapping dangerous boards... shoot away!
