Not sure whether i played this hand badly or well

both the raiser and the caller are both pretty loose, standard pokerstars players.
Do i need to jam river? I think so, i think his calling range is very wide as i do kinda look like i have AK with the action pre flop and on the flop.
Opinions please

. Oh and i know i lost the hand, so i promise i'll post a winning hand up soon
