I thought the original skin was pretty good except for a few areas that I decided to change(mostly the face). Kudos to Turiel for making such a nice model.
Well, its not the way I do it, but I think that you can simply go into your warcraft directory and replace the original skin file with your edited one.
For custom models, you can use the folder system, where you put the place the model somewhere and then lay out a system of folders with the skin path and place the blp in the last one.

This skin is ubber, like 95% of antiheros skins, I would like to be as good as you are, hope you may make a tutorial once ^^, or may you know some good, or may you are so generous and say "Hey I am gonna support Bloody a bit ..." and we can talk about skining methodes.
