What do you think of my story so far?

kind of you shoeld put. He walked up a noisy corridor, a m of kids were running around between cles.That's all tat i think is wring. But good plot.Add a bit more detail on the action scene. Like as martin scrambled to get his books,greg lashed out, the tip of his hard shoes collided wit martyn's head. Blood dripped out, pain was agonizing, Martyin and Greg both knew one thing...Martin's head was cracked open...
