For those that still cannot tell the races apart (which was pretty straightforward for me to be honest), here's the hint - they're sorted in alphabetical order, except for Nords, which are on the two last pics.
So: Argnonian, Breton, Dunmer (or Dark Elf), High Elf, Imperial, Khajiit, Orc, Redguard, Wood Elf, Nord.
So there.
Also - in my opinion elven races look best of all the TES games to date, and I've played them all (my Arena floppy disks say so at least). No more jaundiced, glowing Altmer, no more tame looking Dunmer, no more muppet-show Bosmer!
...so good in fact that it made me consider choosing a different race this time, other than my beloved Breton.
PS: Also don't mind all of them looking gruff the slightest... in my opinion the over-sweetened, mangoid modifications really don't work well in TES. Besides I'm fairly certain that with this system there's going to plenty of room for making your character's apparent sex as ambiguous as you want...
