jeez, where did that come from? despite its randomness, i really enjoyed it. I agree with ecwix's comments, though, and don't feel like re-typing them in my own words.
great writing :)
you should put it into a longer story, though, to give it some context.

Hmph. Not bad, I suppose, but I think it can be far better.

A few notes:

1.) This is a very short story. You're trying to pack as much meaning as you can into a few words. Following from this logic, one should conclude that every individual word should have as much meaning put into it as possible.

In other words, make sure every word is absolutely essential and contributing to the story.

Let's take your second paragraph:

I lay in the Arena, sprawled across the dusty ground, thrown from my dracoling, [my dragon mount,] and now at the mercy of my opponent. He was already charging towards me on his own red-scaled dracoling, his glaive [(a staff weapon with a curved blade at the end)] held high.

Immediately, I notice that you have sharp, abrupt breaks in your sentence to insert description. This is a no-no infodump. They are completely unnecessary. Your readers should be smart enough to figure things out based on your word connotations and the context in the sentence. Dracoling? Sounds like something dragon-related, probably something your character was riding (based on the fact that he was "thrown" from it). You have the sentence written well enough already that there is no real need to explain what a dracoling is.

Same goes for the glaive.

"It was my one remaining weapon, my scimitar, that saved me (I had lost my glaive when I had been thrown off my dracoling)."

Think about this sentence. Is the part in parentheses really needed?

My Advice: Go through your story again and ask yourself, "Is everything absolutely necessary?"

2.) Less telling, More showing

You have an intense battle scene here, but one of the things I noticed when I read it is that it doesn't seem that intense.

You do a lot of telling. He does this. He does that. There are better ways to do it. Give some sensory details. Let the reader REALLY experience what the character is going through. It helps build attraction for your main character and makes your battle scene all the more real.

He cuts the other guy's head off. What did it feel like? Any other observations? The smell of blood? Did any splash on him?

3.) Contradictions. Contradictions. Contradictions.

"The young die hard, I thought as I ducked the scimitar...Without pausing to think I brought the glaive down to my opponent’s neck."

What? If he didn't pause to think, what was that in the paragraph right before? And another one. Where the heck did the glaive come from? I thought he lost his? Did he steal his opponents? Did he pick his up again?

"For the first time in my life I felt fear."

Right. The problem is, from reading what you have, I don't feel any anxiety whatsoever. Your character doesn't really seemed fazed at all. He executes his maneuvers with confidence and skill, not something one would expect for someone who was supposedly afraid for the first time in his life.

If you can make it so that his victory doesn't feel so assured, it would do so much for the story.

I don't want you to feel like I completely hate your story. I don't. Otherwise, I wouldn't waste thirty minutes of my life going through it and giving pointers. It's just the way I work.

Thanks for reviewing me! :)

Good ending sequence. A bit too wordy and explanatory in the beginning. Next time leave more for the reader to fill in, or start off describing the rules of the arena so you don't have to interrupt later on.

Good though. Impressive

A sharp mind is a toll and weapon- use it.
