The reraise on the river is good but the sizing is terrible. Your betsize only gets a tiny bit extra value when you are ahead and gives the second raiser one more chance to make a raise that will put you in a tough spot.

A larger raise to say 55c is much better and just calling wouldnt be terrible. I would probably bet the turn aswell though unless they are quite tight. High overpairs can usually be played for stacks at 2NL if the villains are just calling down.
