portrait for/OF me

An artist, Anthony H. has asked to do a portrait of me.
He wants to know my top 5 favourite bands so he can listen to them while he's working on it (that's quite an impressive MO).
I'm very flattered.
Also *rather* interested in how it will turn out, from THREE points of view, i.e. as a woman being painted by a man,
as an artist being painted by another artist,
as a person being painted by another person.

{I've put these in the most honest order i can by concentrating on my first reaction to hearing about this; which reveals nothing more than the fact that i am human : )

Fact is, i have never tried a serious attempt at self-portraiture. I have no face in my head for myself, the way I do for other people. I literally cannot see myself as a complete person, altho lately i do seem to be progressing towards some kind of definite iD in my own mental image of myself. But it is never stationary enough to really LOOK at, enough to paint myself. And photos are no help - i just see a different person in each one!

Fortunately there IS a recent photo that I feel is right to be used as working model for this portrait; it's reveals me as relaxed as i can get while still conscious of the eyes of the city, and delighted about being among trees and walking on grass: i'm without any makeup , the place is Hampstead Heath this April and it was taken by the person who, purely by defaut of survival i may add, knows me better than anybody - my long term friend Alan.

So - a happy coincidence: many coincidences lately seem to be concerned with my identity.
I am becoming.
