Nice one

Nice variation of "Cold Times" (http://www.newgrounds.com/audio/list en/112874)

Now it would be perfect if you could do a complete song out of it... like a tiny story (first a slow one ... than something fast ... a depressing midterm ... fast again and a final).
But as for now ... you get 9/10 (no loop / short / aprupt ending)

Agree with Jurian

Definately game music maybe someone will use for a game

sounds quite cool

Maybe in some k ind of a mario game where you have to run for bowser. It sounds nice, good job.

Please listen to my newest song called do you feel the beat

Good song.

but, I wouldn't put this in "Ambient". You got potiential though.
