It looks like you just give up on the BB - it's not a good position, sure, but you could perhaps play it harder.

Your turn AF is too low. Are you giving up too many hands when your cbets are called? A LOT of people's entire 100nl strategy seems to be based on floating then betting the turn. So fight back - either buy position through check/calling or check/raising on the flop; or lead or check/raise more turns.
