Stupid little hand

[TheWorstPlayer]

It's too stupid for me to even convert it, sorry. Can just one or two people tell me if this is okay or retarded? Obviously I try to mix up how I play my sets. This time I tried to take a c/c, lead approach. I assume c/r on the river is standard, or do people lead again. I figured that he would fold an overpair if I lead again, but that he might value bet it if I checked and he would definitely commit himself with a flush. And he might bluff if he had a missed high flush draw on the turn. Yes?
