I would like to see more of Alla, too. She might be Indian. According to some Googling, she also goes by the name "Malvina Newman". I've not found any large pics of her yet. She appears in a few videos from nylondvds.com.
Good luck with the search!
Update: A good BT feed of her is available here...

Contains five full sets from ATK exotics. Interesting because it appears the model profile you linked to only links to one set. Maybe other sets are from the other AM Kingdom sites, like the hairy one.
