I also have a survival backpack with similar contents. Because the weather here can get pretty cold & nasty my emphasis is on warmth:

socks (ironraven’s suggestion)
wool or fleece toque
mittens
plastic bags (med size) to pull over your dry socks if your boots become wet
extra clothing (fleece is very warm, light & compressible)

Try to imagine yourself huddling against the wind & rain, chilled & miserable, what do you need/want to make it through the night?

Rope & carabineers give you flexibility for shelter set-up
Small pad to sit on (you want something to keep you off the ground)
Hammock & tarp are interesting shelter options

I use my pack on a regular basis when outdoors, it allows me to evaluate it and improve the contents - change them according to seasons...

cheers!
