I posted a request a few days ago asking for a Blood Elf to "Dark Elf" skin change, but decided to go ahead and try to do it myself in the meantime.
I followed Lex's Reskinning Guide, and I was able to successfully reskin a tauren bear form (as a test), but when I tried to reskin my BE, all I got was a normal face and a solid green body.
Here is the image of the .BLP file I changed

After some thought into this I decided that maybe I had to change the other .BLP files associated with the Blood Elf, such as a specific face, torso, etc., but I wanted to know the specifics before I started randomly changing things.
Please note; if there is a guide concerning this topic, I am sorry but I have not found it. I have only found guides for changing creature skins, which are apparently simpler than character skins.
Thank you in advance!
