100NL river push ok?

[veryblind]

Live 100NL with passive preflop.

BB(villain) ($200)
UTG(hero) ($450 chip leader)
UTG+1 ($400)

Preflop: I limp UTG with 5 [img]/images/graemlins/diamond.gif[/img]3 [img]/images/graemlins/diamond.gif[/img], UTG+1 limps, MP1 limps, SB completes, BB checks
Flop ($10): J [img]/images/graemlins/diamond.gif[/img] 5 [img]/images/graemlins/club.gif[/img] 2 [img]/images/graemlins/diamond.gif[/img]
checks to me, I bet $15, UTG+1 calls, BB calls

Turn ($55): A [img]/images/graemlins/spade.gif[/img]
BB checks, I bet $30, UTG+1 folds, BB calls.

River ($115): 5 [img]/images/graemlins/club.gif[/img]
BB bets $35, I push

I got lucky obviously and my preflop play is questionable. But I felt I had a good read on the whole table. What do you think of river play?
