Okay, I've decided to be brave and post a little something. I want this particular passage to convey fear, terror. Now, it doesn't take much to scare me, so I don't think I am very good at writing this particular kind of thing, but my MC is supposed to be terrified here. Comments are welcome (well, nicely phrased ones anyhow)

Min hurried out of the room, careful to replace the tapestry that hid the entrance. She was backing away, making sure that there was no evidence of the door, when she heard the distinct sound of footsteps coming towards her. Min froze in alarm. Though her mind knew it was probably just another student, or one of the instructors or servants, there had been too many stories of late of strange noises and ghostly lights. Min held her breath as the footsteps came nearer. She quickly blew out her candle and pressed herself into the wall.
The footsteps grew louder and stronger until at last they stopped only a few feet from where she hid next to the curtained window. An invisible hand reached out and twitched the draperies aside, letting the strong moonlight spill into the corridor. Min could make out the large, dark shadow of a man. Though she tried to keep silent, her breath came faster as her heart beat in desperate time to her panic. The shadow lunged at her. Min opened her mouth to scream, but the sound was cut off by the pressure of a very large hand.
Her head swam as her terror clawed its way through her body, but she began to kick and twist frantically as the shadow wrapped its arms around her.
