-35bb/100 isn't too bad. You can prob defend more, esp. by 3betting and prob need to play flops more agressively by x/r.
You should be much more concerned with your WWSF though. Unless you're playing a ton of multi-way pots in super soft pools (and even then) that's just way too low. Same for W$SD. Seems youre calling too much or making bad bluffs/bluff too often etc.
