BB Special with a C/R

No read on the button. He just sat down a few hands ago. Seemed to be very passive as he has called through the streets a few times with mid-low pair.

Final Pot: 8.25 BB

I felt everything was standard here. I threw in the turn C/R because he bet on the flop AND because I completed my straight.

I don't think I did anything wrong here and since he called the turn, there was nothing I could do about the card on the river (because it was not free).
