Tricky hand 100NL deep stacks

[loewfat]

Opponent wasn't extremely good, but was decent and had a wild style. He would often totally randomize his play, but I was constantly getting the best of him by value betting and being extremely agressive. I'm fairly confident that I made the right laydown here. After he called my big raise on the turn I was praying that the river wouldn't be a heart or pair the board, and unfortunately it was both. Any and all thoughts would be appreciated.
