Met calls her Alena A. She appears in 5 sets by Chepurnoy, all published in 2005. There has also been at least one set with her on domai, who call her Aleka. I don'r know that she has a thread on this forum.
The AmourAngel pics that you found happen to be identical (yes, identical - not just similar) to one of the Met-Art sets, published 21 Feb 2005.
BTW - FYI: photographer Chepurnoy died last December, so I read on a russian site. We'll greatly miss his talents...
