Ive tested this thoroughly. For the quickest reference use the velious fashion page. There are six faces lined up. Whose faces are exactly aligned with which face you get when you race change using the illusion spell.
However two problems to note with that method. Number one is there's only six faces shown out of the eight. Number two is that helmets obscure some faces. I will tell you the helmeted dark elf face is the one that belongs to the very deep red eyed mr spock looking face.
Another method that you can't do one blue anymore now but works on the easy server is to use a quickly leveled up chanter to cross-reference the illusions while using the face tab to switch faces. Be careful doing this method and make sure you Zone before you check each time because the first time you cast it that face will always come up even if you change using the face tab
Finally if you just show me what face you want to have as a dark elf I will show you what face to get with whatever race you want to play
Here is a human example of what I meant for the fashion page (I cut out the helmeted plate guys):
