I'd say you did quite well in conveying a creepy, sinister atmosphere. lol That is hard to do in such a teeny, tiny format.

I liked the 'silent' whispering. Great intro and attention getter.

The 'Darkness closing in' is also good for invoking creepy and mystery.

The 'ice wind' helps to complete the creepy feeling, however, it made me really think about the mental issues that would make someone feel icy cold. Very puzzling and again, held my attention.
Thanks for sharing.
