Gorgeous!

And This is the Jessi that really impresses me:

Both so real and so beautiful.

I have to admit, though that the image posted by Tiari is a wonderful fantasy image of Jessi, really amazingly beautiful.

Alas, beauty is in the eye of the beholder.  I love all women, so picking a favorite is very tough.  (I run into this trouble in real life too!)

Cheers!
