The fact that you have a vest rig makes me jealous! Good looking for the most part I would say. Though being on a vest, I would opt for the lightest effective gear I could get my hands on. Budget, and local availability are factors of course. Just ideas. Take them as you will of course.
Things I would do:
Cut that toothbrush down.
Toothpowder is more compact, and lighter (generally) than tooth paste. A little goes a long way.
Unless the razor serves a purpose other than cleaning up your stubble, I'd pitch it.
The signal mirror is kind of big. That might not be an issue to you though. If you wanted to go quick, dirty, really light, and small, it is possible to improvise one from a CD or DVD.
Instead of the three piece cutlery set... perhaps get a titanium spork, or a Light My Fire polycarbonate multi-spork thing. Of course, the knife part on the multi-spork is limited, and there isn't one with a Ti spork. However, if you already carry a knife otherwise, and feel comfortable cutting your food with it... why not cut it down to one dedicated eating utensil?
If you don't have a canteen cup, get one. It can replace your pot... save you some space to pack something else in.
Not sure how big your camp stove is... but I know they make canteen stoves that go with the canteen/cut/carrier combo. Might save you some space as well. ESBIT maybe otherwise? Small, light, relatively compact. You can burn ESBIT tabs, Trioxane,or Hexamine on it. It does work to boil water... but you might want some tinfoil as a windbreak.
Like I said, just suggestions... if you like them, and they suit your purpose, awesome. If not, well, no big deal.
