Asides from going a little big bigger on the flop and turn, your line is perfect. Donking into 4 players and c-r are both fine lines here, if donking I would make it bigger though to 85% pot.

Looks great.

I much prefer leading multiway on these flops rather than risking it getting checked around with draws taking a free card.

The river shove works well here with all the flop draws whiffing. There's not a lot in his range which will call a third barrel anyway so why not maximise value for when he does and induce a hero call more frequently too.
