raise more preflop. loosen up a bit. you can have a vpip of 20%, even more in a $2/4 game. completing more hands from sb will accomplish a lot. usually you have odds to complete 40-50% of the time in $2/4. other than that, seems you are properly aggressive, though only winning 26.5% when seeing the flop is cause for some concern. you may just be on a bad run, or you may be paying off too much. premium preflop hands can begin to look awfully bad with some flops, and many times need to be dumped. since you are only folding 6.88% on the flop, i would say this is the case. if you can bring yourself to fold more flop bets when you don't have the odds to call, you will save $$$$, thus adding to your win rate.

cheers!
