As Saintly Steve says, it's not just about looks.
A woman's true beauty is in her heart and spirit and I see an inner beauty inside Amy Macdonald. As far as looks are concerned I think her eyes and mouth are physically very attractive but it's her disposition which shines through and is so attractive.
She is animated and vivacious. If I was in her age group and knew her I could probably fall in love with her as many others could.
