This looks fine, but you can probably bet a little more on the river, like near pot.

He'll have a king (maybe KQ) that can't let go on the river a lot of the time, a busted draw some of the time, and Axd that will definitely call with TP, so bet a solid amount here.

Not a bad river bet to make sure you get a call. I thought it was slightly smallish but otherwise just fine.
