Here are a few tips on surviving in the wilderness. If you are lost, DO NOT go far from where you are. If you have means to start a fire, you should only go about 30-40 feet and you should make sure you have A TON of wood because you probably would not want to tromp around in the woods 40 feet from a dying bed of burning coals in the middle of the night, While you can't see. So if you're lost, just make a small wood pile near your fire. If you are hurt, try to move around as lightly on the broken limb, so you might be able to gather materials to start a fire.....and a smokey one at that!
Fire: Besides the candles, I don't see any tinder in this kit. If you replaced that wood with an equal amount of tinder, it would start a few dozen fires. However, that small pile of twigs you have there would barely last 20 minutes, IF you managed to light it. The forest floor is littered with tons of deadwood, but dry tinder is much harder to come by. Also, matches suck. They're a good last-ditch item, but please don't rely on them. Get a firesteel and a lighter.
Shelter: You have plenty of cordage, which is great, but that disposable poncho wouldn't even hold up as a trash bag. As a matter of fact, you'd be better off with a thick garbage bag.
Tools: You definitely need to invest in a good knife. Hell, go to Walmart and get the cheapest hunting knife they sell, for all I care! Anything would be better than that sheet-metal steak knife.
You seem to have somewhat covered signaling/navigation, first aid, and water collection/purification. 3 out of 6. Not bad.

for instance the poncho wouldn't hold up long in a slight breeze, nothing to boil water (the tinfoil would fail fast) so your looking at dehydration, a kitchen knife. your looking at 330 stainless at best, would lose its edge if you sneezed on it.
id go on but i dont want to sound hateful. look at my kit for the basic needs. and look at punkhead58's kit and airth's kit for something more comprehensive
