Good kit! Nice and basic.

There is a tube filled with spark-lite tinder in the kit. (nice trick with the zip-tie BTW)

Somethings I would add are some safety-pins and a couple of sewing needles.

A coffee-filter would come in handy to.

In what can you boil water? Maybe add some HD aluminium foil

Do you have a poncho or other rain-gear with you in your regular hiking-kit? If not, I would add a emergency-poncho.
