Imagery to present a character

Hey guys, long time no see! 

It's Lydia here!

Let me know what you think of this piece I wrote on Friday, it was homework from my creative writing class. 

Leave me a comment if you have any opinions to voice.

Can someone clarify the definition of beauty?

 I am not beautiful, my nose is wonky as a bent wire, and one eye is emerald green while the other is pastel blue. I do not have an crystal hour glass figure, its dumpy on top and balanced on thin legs like that of a child’s crayon drawing or a famous Picasso piece. My arms are hard and thick like leather and my hair is not long and luscious, but stubbornly rigid and straw-like.

I am not beautiful.

Yet the girl who sits across from me, Nancy, yes I think her name is, has white moon skin that shines like a light bulb in the mirror, while pinpricks of red blemishes are dotted about her cheeks as though droplets of blood on marble. Her features are structured and cohesive as if God made her with a protractor and ruler, the nose is high with balanced bones, and it curves like a silver spoon to meet a small pink sphere, and each eye is equally blue. Her face is shaped like a cut out heart, sweetly round and sinuous, that meets to join the hairline, the colour of coffee, with faint lines of fire orange that continue to the ends.

 Is this what perfection is?

How can this be while her insides bubble and boil, like an old hag stirring a caldron. With thin snake like wrinkles, that etches out like fork marks that reach her dying, dull and moldy eyes. Her skin isn’t a firm jewel, but limp and loose like a living corpse, with the colours of decease, a yellowing gray form with ageing purple bruises. Her body is bumpy but solid, as her skeletal form peaks beneath dusty skin. It seems that vanity has eaten her decayed soul, as the beast eats the innocent.

Inner beauty is something more I wish to harvest; the beating gold heart is of more worth than a full face.
