Observed hand...please comment

Pre Flop: He's playing QJs more agressively than I would but seems it's his style.

Flop: I like the lead. He potentially disguises his hand if the flush hits and gets called by smaller flushes.

Turn: Standard. He's improved on the turn after a flop that isn't that scary.

River: Really good bet and raise. Button is not putting him on a flush and will likely call with lesser hands given the way he is betting...
