Final Escape (WIP)

Okay this is a rewrite, critique it as much as possible. Seriously, rip to shreds!! >3
(and it's unfinished)

She had failed. She had failed herself, again. Leks tried, repeatedly, tirelessly, but she could not do it. She could not hide her fear. She could not hide from their evil stares. They would peer through the small hole of a window in her cell door... and they would laugh. It must have been so amusing to watch her struggle with herself. Leks fought to keep her breathing steady. She tried in vain to block the sound of her fellow demons crying in agony or screaming in madness. She did her best to ignore the stench of burnt flesh and corpses. It all failed.

The cell was small, and dark, and all the shades of black. The floor and the walls that surrounded her gave Leks the impression of a small natural cave. Once, she had tried to believe that was where she was, and not in a labyrinth of prisons, surrounded by torture and death. But it failed. Of course it did. A cave would have felt cool, but the black rock exuded waves of heat. So hot, that the airs near it visibly danced; as anyone would dance, if they were made to wear hot iron on the soles of their feet.

Sweat covered her red, dirty skin. Her torn grey garbs clung to her. Short black hair stuck to her face, irritating her cheek. Leks could not do anything about that, as her ankles and wrists were bound to the ground with metal manacles. They must have been gleaming silver once. Now they glowed red. Her tail was pinned down at the tip to the floor. With what, she could not see. Among the masses of unkempt hair; two uneven off-white lumps poked through – the remnants of her proud horns, her now, broken horns. She distracted herself from the humiliation many times by concentrating on the searing pain she felt on every part of body that was touching the ground.

Two red eyes emerged in the small window of the door. Leks recognised them. Those eyes belonged to a prison guard who frequently tormented her. He was usually accompanied with others who guffawed loudly at his verbal and physical abuse. The eyes burned with fire so fiercely that Lek’s own green eyes leaked blood tears. She felt the cool liquid streak down her face. Some travelled along her nose and unto her lips. Others lingered under her jaw and fell to her chest.

Even though only his eyes could be seen through the small hole, Leks sensed his cruel smile. The guard suppressed the demonic flames. This time they burned with a different fire. Without breaking eye contact, he opened the door. As expected, he was smiling at his handiwork. However, there were no other demons with him. Why did he not want an audience today?

I think you did well in describing this one event going on. I felt though that you used too many sentences that ended in simple words like "It didn't." and would be followed by a series of these. I know most forms of writing involve this, but I think there was one too many in this piece. ^^; Also, I don't know if it's your style to use elipses, but if you do, give it a try. It tends to add a dramatic pause to writing.

For instance:

She did her best to ignore the stench of burnt flesh and corpses. It all failed.

could be
She did her best to ignore the stench of burnt flesh and corpses ... It all failed.

Kind of adds more of a pause to it. Other than that, your use of imagery is still great. :3 Keep at it.

I agree with Felix.
Add those itty bitty edits and this shall be perfection, Rieal!
