This hand came about earlier whilst I was playing, how could I of played this better?

Folding on the river did not seem like the most appropriate play at the time, but I feel I am mistaken here. Obviously I was betting looking to extract value from flush draws, which finally got there on the river so once it came about I was unsure how to act facing a bet on the river. Any feedback is appreciated.
