If you're going to re-raise the min raise preflop, make it like 4 or 5 times the first raise amount... but only because it's a min-raise. Re-raise 3x the raise amount (like you did here) when the first raise is like 4 or 5x bb.

You bet 2/3 pot on both the flop and turn, this is good. As for the river, I'd either lead for 1/3pot or check call.
