| Hmmm... you could phrase these as Immediate Reactions triggering off of the event ("An ally within 10 squares of you takes damage" and "You take damage which decreases your hit point total"). That way, when the start of your turn rolls around, you don't need to say, "Hey, wait, did anybody take damage that round?"
Both abilities seem very strong for feats. THP are very powerful and the triggering conditions seem like things that would happen a LOT. These might as well say "You get X THP at the start of each round," which seems very strong. I think I would either limit these to once per encounter. OR provide a bonus to the THP provided by BattleRageVigor; for example, when you get BRV THP, if [an ally | you] have taken damage since last round, you get extra THP equal to your Wisdom mod (you don't want to double-dip Constitution), or maybe equal to +2 (sometimes a fixed value is better than an ability mod, especially for feats, which tend to give fixed values and have ability prerequisites).
I really like the flavor, though. You could develop an entire line of "Personality" feats where you get some bonus in some circumstance based on personality traits. It might encourage more role-playing in certain players.
