Keep the aggression vs. small paired board?

[smizmiatch]

Villain is loose passive.
Is there any point in this hand where I should ease up the pressure? It's a large multiway pot, but no one shows any strength until the very end.
Should I have bet the river like I did? I think it's for value.
Thanks.
