What do you think of this story (it's long)?

(I made a story based on one of my "What would happen next?" questions from a couple weeks ago. I know, it's long, so if you don't like reading, just do yourself a favor and click the Back button. Also, I wrote this without proofreading, so just ignore any bad spelling or grammar.)

For ages the war has carried on. For ages the forces of life and the reborn forces of death have clashed in battle. Death cannot die, yet life refuses to hide from their fears of their demise.

This is the six hundredth year of the war between the living and the undead. Few of which remember the wonders of peace remain living, all the rest being killed through age or war. Men and women, boys and girls, and nobles and beggars have each been thrown into battle. The world has been driven into chaos, as has its people.

The undead march through the gladded realm of the Light Elves. The Elven people become overwhelmed, and are driven into a nearby desert where they plan to flank there enemies and return to their turf where they can fortify their borders and drive away the remainder of the enemy. This plan is highly unorganized, and the aid of the living is too far away.
Above this desert, upon a tall dry cliff thousands of feet off the grounds of the battlefield, a beautiful Elven maiden finds herself cornered by an undead lich. She is armed only with a mere dagger, and is encased in a beautiful bright blue dress which enlightens her beauty even more. The steaming sun increases the warmth of her body, and burns her skin.
She stands hopelessly in shock as her satanic oppenent floats off the ground with pleasure. The monster wears a dirty, tattered red robe of which exposes much of his decaying skin. His red eyes and skeletal face glow through the darkness of his rusty helmet. Many charms and gems dangle at his deathly wrists. In the lich's left hand is a tall, magical staff. A golden sword makes itself home in the other hand.

The lich lunges his sword back and forth in attempt to slice the flesh of the helpless maiden. Her agility guides her, and she remains unharmed. Acting quickly, she leaps upon a rock nearly three yards above the cliff, as the mountain is very tall. The lich merely floats higher as a bolt of lightning flies from his staff, just missing the head of his victim.
The woman leaps onto another boulder, only to be followed once more. Another bolt of lightning screeches by her face, causing her to look back and find that the lich continues to follow her. As she looks up, she find that a random branch is stuck within the stones of the mountain. She leaps for it, successfully grasping it. However, a small crack is heard by both her and her enemy. The lich grins, casting a load of lightning at the branch's base.
It snaps.

The maiden falls hundreds of feet, thankfully landing on another edge. The lich floats down with a joyful expression covering his evil face. He raises his blade for the final strike.
The maiden, desperate, unsheaths her dagger and rolls over in order to dodge the lich's blow. The swords falls from the lich's hand and plunges itself into the stone of the cliff, causing the ground to crack. The woman's eyes grow large as the ground crack ever more, and the lich prepares to strike another bolt at her.
Slowly, the lich raises his staff in a harmful gesture, exposing his decaying chest. The woman quickly forces her dagger into the lich's flesh. The monster freezes in motion, dropping his staff. He looks into the woman's eyes with sadness, anger, and fear. Slowly, an arcane orb becomes visible deep within his body, growing in size by the second. Finally, the beast detonates, sending the edge, with the woman, thousands of feet out and down into the battlefield.
