NL50 3handed - QJo OTB line?

[RedBarracuda]

Hero:$54
SB:$37
BB:$49

no reads except that I saw in chat that villain was complaining that he doesn't get good hands at this table, or some crap like that..

Hero OTB with [Jh] raises to $2.50, BB calls..

flop [Kc][Ac] ($5) .. BB checks, Hero bets $4.50, BB calls..

turn ($13.55) .. BB checks, Hero checks..

river ($13.55) .. BB bets $5, Hero raises to $16

Is this standard ? I am concerned with my river raise.. should I make it more, $25ish?

My standard opening raise is to $2.50 at NL50 .. and honestly, I don't intend to change it because there are way too many callers if I raise to $1.50 or even $2 .. I assure you, both SB and BB would have called here had I raised less, AND, had there been full 6max, probably one or 2 more people would call... also, I feel comfortable by raising to $2.50 and then CBing strongly... it's just my thing I guess..
