Final Pot: $38

This is a pretty clear-cut hand. I raise preflop and hit TPTK with Queens. I reraise bet from SB. Turn comes a heart and this is an obvious check/fold when I got 1 caller behind me on the obvious flush draw.

What I'm wondering about is if my post-flop raise was too small. Should I have raised more?
