You seem to be losing a bit more in the BB than most around here. You might work on your blind defense some. Try to get it up into the mid teens (but still negative, of course). SB looks pretty good. An extra 0.05 BB/100 in the BB once every 6 hands could affect your winrate substantially. I'm still a blind defense n00b, and my BB winrate is -0.14 BB/100.
