Stars 10 10 min...River bluff line...is this pretty standard?

[ssnyc]

Stars 10 10 min..about 400 left...I've been all over (down to 105 at one point) and scraped back up to a medium stack...been playing pretty aggressive pre but not too many post flop moves...villan is new to table so no real reads.

on the flop I called the small bet with 2nd pair cause he was last to act and I wanted to see what he did on turn..

after turn I was thinking he had a weak Q or a 9...river makes the flush and I figured my line looked like a FD and that he wasn't strong enough to make the call...

Is the line okay? I don't make many moves but this seemed like a ripe spot.
