As a fellow fan of WoW TF TGs I hope you do many more of these.
If you really enjoy doing requests, some I'd like to see are:
Human guy takes a bath in a moonwell, becomes a night elf female.
Guy gets infected by something in the plaguelands and turns into an undead female.
Pressing the wrong button in Gnomeregon turns someone into a female gnome with pink pigtails.
