5/10 NL Pot overbet

[FoxwoodsFiend]

Villain is complete donk in LP w/1400. I've taken a few hands off him and he's out to get me. UTG has 1K, I have 2300.
Hero is UTG+2 w/4 [img]/images/graemlins/club.gif[/img] 5 [img]/images/graemlins/club.gif[/img]
UTG raises to 20, Hero reraises to 55. Villain calls, folded to UTG who calls. Flop comes 2 [img]/images/graemlins/diamond.gif[/img] 3 [img]/images/graemlins/spade.gif[/img] 6 [img]/images/graemlins/diamond.gif[/img]
UTG checks, Hero goes all in for 2245.
Anybody think i'm playing this too strong?
