PLO8, Flop play

Long time lurker, first time poster. I've always found the advice to here to be top notch, and I'd like some advice on this situation I ran into.

PLO8 .50-$1

Hero has A [img]/images/graemlins/diamond.gif[/img]3 [img]/images/graemlins/club.gif[/img]5 [img]/images/graemlins/spade.gif[/img]J [img]/images/graemlins/spade.gif[/img] from the cutoff. I open limp, button calls, blinds call/check.

Flop comes 2 [img]/images/graemlins/heart.gif[/img]4 [img]/images/graemlins/heart.gif[/img]J [img]/images/graemlins/diamond.gif[/img]. Blinds check, I bet the pot, $4, button repots to $16, blinds fold, back to me.

Any advice?
