I'd like the flop bet to be just a bit bigger. If he also flops a flush draw, you've given him odds (including implied) to chase. I have no problem with the rest of it, except maybe the preflop call. If you felt like he was stealing, maybe reraise preflop. If you weren't sure he was stealing, you'd be better off folding. You are only going to flop that flush draw one time in nine, and with your one-gap the straight draw odds are thin as well. More likely you'll be out of position, having already indicated your hand is weak by not reraising preflop, trying to figure out if you should stick with your middle or bottom pair and low kicker.
