I like the story so far, and ill give you a little imput. try using a different way to describe what the character is doing for example:

"I looked at a alley and saw a boy about my size and a man. I already knew what was happening. The man lifted his hands that was turning red. I gasped.
I didn't gasp because I was scared or anything like that. It's actally very normal for people to find a wizard and a poor, defenseless human in any type of alley. I watch the strugling boy be force to go up into the air. I then turned around and took a few steps. I turned back around and started to run. I got to the edge and jumped off. I flipped about 20 times before I landed on the ground."

could be changed to:

Gazing down into the alley i witnessed a scene all to familiar in these times, a helpless boy and a wizard, hands glowing red and ready to strike. I watched as the boy was forced into the air and i took a few steps back. As i turned back towards the alley i began to sprint and inhaled deeply before launching myself off of my perch, twisting through the air with the ease of an acrobat.

just a suggestion though. it seems to me like your trying to make things longer than it needs to be and you can still get all those details you want people to have if you shorten it up a little bit. Anyway im looking forward to more and i will be glad to give you more of my input if you want it.
