Sentinel/Protector sounds more suited for a Skill Book rather than a Talent. Remember, Talents are passive abilities.
Stinkly cloud is way too debilitating for allies. I don't think we should make that idea happen.
Quick Reflexes / Awareness / whatever you want to call it, a Talent for +10 initiative - need more opinions on this. Is it OP? Underpowered? Should have additional perks or keep it simple?
Quickdraw sounds good, I'm all for that. Would open up really interesting hybrid playstyles.
Ugly Duck doesn't make sense to me. Besides you've already got Leadership perks to buff your allies.
Looking at the OP, Grounded looks like another candidate for the "buff this talent" category. Much like Ice King and Demon, it should probably have an additional side-effect. Perhaps Ice King ought to grant a buff to magical armour (instead of physical armour) and we'd relegate the physical armour buff to Grounded?
