First of all I don't like your limit style raise preflop. Make it at least 3xBB to go.

Second of all, on the flop, you should worry about someone having a 4 (since your weak raise preflop people are gonna call with mediocre hands, as weak as 45s at these low limits) so you should bet the pot. Just stick it in, if someone calls or raise here you should slow down a little.
