Alright tough cat, time for debunking here x).
I say those boys up there are right, the model is nothing different and I can prove you right here.

Click on the picture for better view, Freddy don't have a wrap in his arm and no flying bubble (farts?) but somehow have the same hand.
You do watch Friday the 13th right? You know Freddy wear a glove right? I can understand no hat but this enough to tell you zombie isn't model the best use for freddy and you rather make it a custom model instead. But here'a thing, I am using your own model to compare here, but I can do the same thing as a Skin by simply do the one below here.

You just need to alpha out the bandage and the bubble to get the same result without making it as a seperated model.
When upload back as a skin, texture path should be: units\Creeps\Zombie\ZombieA.blp
This will replace the zombie texture.
That's the solution: Upload the blp only with the change i have provided for you.
About the "texture" itself, idk do you have evident this is made by you or not, look like you crop someone eye and put in there with burnt skin CNP all over the place.
