In general, well done. It is surprising how few people actually assemble a basic kit for home, car and personal carry.
A few observations and suggestions for addition or subtraction from your kit:
WATER:
The water bag looks fairly thin skinned and you only have one. Assuming you lose your canteen, I'd recommend a more sturdy vessel with a thicker plastic that can still be folded. Collapsible multi-quart containers will still fit into the size you have available, or have several of the 1 quart containers since it can be guaranteed you will spring a leak and have to use some of that duct tape on it.
FIRE TOOLS:
A 2" bar of magnesium and some more dry emergency tinder to use with your ferrocerium rod can be a lifesaver. Matches have a few uses, but if you are pushed for space, another lighter would probably be better. You can light perhaps a hundred fires with a lighter, 10 matches might light 8-10 (a few always break, get wet, etc.). As referenced before, having more tinder on hand is probably preferable, since finding something dry to use when it's cold and wet out just drags down your energy and demoralizes you. The fresnel lens works pretty well for finding that splinter under your skin and can start a fire, more reason for augmenting the tinder and adding some magnesium to boost the tinder.
CUTTING TOOLS:
I would recommend replacing the striker with a multi-tool. You can use the file to work the ferrocerium rod instead of the knife blade, also the multi-tool should contain a saw blade, which replaces the awful wire saw. This also gives you a wire cutter for the snare wire and a way to cut all that cordage and monofilament line. The wire saw will last maybe through one or two uses. Even if you are diligent, the wire gets hot during use and any pressure applied to the wood limb will curl the ends of the wire saw towards you, fatiguing the wire at its center and ultimately will lead to it snapping. Wire saws sound like a lightweight solution to the problem, but it's not something I'd bet my life on.
TRAP/FISHING TOOLS:
35 feet of snare wire is probably sufficient (50 is better), but you really need more general purpose cordage. 550 lb paracord, monofilament 50+ lb line and lots of it. Almost everything you have in that kit should be wrapped with some kind of cord or line to save space. Snare wire has it's uses, but you don't have enough to help with tasks such as shelter building. Also, how were you planning on cutting the snarewire? The multitools have a wirecutter and pliers to bend the wire into tight curls or knots without cutting your hands in the process (thus my suggestion for inclusion). The good snarewire can take a LOT of bending to break by hand and you can cut yourself when it does.
TOOLS:
The mini prybar is probably dead given the length. If you needed to get into our out of a car or home in an emergency, a rock through a window will do the trick. If you really want a prybar, get something in the 12" range, outside the kit, in titanium if weight worries you and hang it off your belt (don't leave it in your car, if you are ever stopped and you agree to have your car searched, it could raise suspicions as a "theft" tool).
MEDICINES/FIRST AID:
The Immodium is a good choice, since diarrhea can significantly slow you down as a result of dehydration. Worst case, if the dehydration is severe enough it can kill you in a week or two. A more moderate case will make you miserable and ruin your productivity in setting up traps, collecting firewood or finding your way out of wherever you are. The Benadryl may be important to you if you have known allergies. I would recommend some decent pain killers, max strength Tylenol or generic acetaminophen and generic ibuprofen (both in the 500-800 mg range) can be taken together (one each) to knock out some of the pain of most non lifethreatening injuries. You may also want at least some topical antibiotics, since nicks and cuts are more or less guaranteed and an infection in the middle of nowhere can become a very bad thing. My recommendation is to add more first aid items to your kit, even if you have to make some tough choices as to what you might have to remove.
I see a sewing kit, but it's not declared. I'd recommend a skin sewing kit in case you open up a wound that needs it. The type of needle used for that work is curved and you'll need some disinfectant before you use it. You can clean off the needle nose of the multi-tool to use as a makeshfit suture needle grip so you can see what you are doing.
As for your knife collection, not a lot of "use" showing on those hard use knives. Time to go to the woods and get them dirty!
Keep up the good work.
