Nice kit! I might add some more shelter components (Bivy, heatsheets, rope, blanket/sleeping bag, mattress, etc.), a saw or hatchet, and something to boil along with water, like tea/coffee/hot choc/broth.

I'd also consider the sun and the bugs. Bug juice, netting, sunscreen and/or long pants/sleeves might be a welcome addition while waiting for rescue or self-rescuing.
