Weird spot with Q-high flush on the river with a paired board

[SneakrFreakr]

No reads or stats on the villain apart from the pot we had a few minutes before this hand happened (should've bet more on turn):

I've been playing quite agressive (I've been at the table for just a few orbits), running about 22/18. What do you think about it?

Fold

I think this is a fold. Don't know if i could make it at the table though. Unless villain is very aggrotarded he has a better flush / boat way more often than a lone 4 or a lower flush (or air).
I would have bet a little bit more on the flop and turn.
