do you just want to analyse the river here, since preflop is the only good part of this hand?
Bet more on flop for starters, ~$2
Bet hella more than $1.50 on the staightening flushy turn ~3 - $3.50 as played, ~$5 if more is bet on flop
check/re evaluate river depending on size of opponents bet (Most likely folding to any river bet that isn't ridiculously small against someone with no reads or stats on) . I don't see why you would bet behind the check tbh, unless you have a sick read putting him on a,q, your getting very limited value.
As played, easy fold to re raise, this aint ever a bluff imo
