Bottom set facing all in

Villian seemed solid although this was fairly early in my time at the table. Over 203 hands he ended up 23/3.4/1.4

Final Pot: $215.10

First off is my raise to small on the flop? Maybe more like $15. Then does anyone find a fold on the turn? Overpair probably reraises pf. 2 pair seems unlikely on this board if we consider the villian unlikely to make any unreasonable calls pf.
