How to analyze a HU session?

[ElSapo]

I have a heads-up session where I got slaughtered, losing about 30 BB in 40 hands. Can someone suggest a way to sort of analyze this as a whole?

Looking hand by hand, I see plenty of spots where I bluffed at the wrong time, but I don't know if this means they were bad bluffs or bad luck. Largely card dead, but I want to find spots I could have won more or los less.

Suggestions?

EDIT to add... I have PokerTracker but no other software.
