-Hair covers right eye, no depth perception.
-Spikes on right hand, less overall useability as it would impact dexterity. It also appears to be heavy.
-No tears on clothes, unrealistic in the post-apocalyse.
-Too clean, also unrealistic.
-Chunk of metal strapped onto left hand, also looks heavy as well as bulky.
-The normal-ish clothes that he does have aren't suited to such an enviroment. It appears he's either wearing no socks or too-small ankle socks, which isn't practical for walking long distances. If he's going to be walking, he should also be wearing boots.
-Pants are too tight, would get rashes whilst walking long distances.
-Jacket is unbuttoned. If it's summer, he should have it in a pack, and if it's winter, he should button it up. I'm assuming it's winter, since he's also wearing one of those thermal face protectors, so why isn't it buttoned up? If it's summer, why's he wearing it?
-Why the hell does he have two swords? A singular machete I could see, but two swords? That's a sizable amount of uneeded weight.
-Is that a ghost?

Overall?
3/10. Cliche, most things seem to serve no use.

one of the swords is actually a large knife, the one on his hip. it's not a jacket he's wearing either, he's wearing a light-armored shirt. the metal on his hands are made from scraps, giving him a sort of junkie look. the face covering isn't thermal, it's also armor, meant to protect his face and neck. The spikes on his right hand are a last resort if he loses both his knife and sword and if he's out of ammo, though he'll use it from time to time. The knife is also a backup, the sword is his primary way of killing zombies since it's quick, quiet, fun, and efficient
