Wow. Your use of imagery is absolutely excellent. Not to mention the creativity to come up with something like the creature. There were a couple of places where you repeated a phrase twice within two sentences but that could be easily fixed. For some strange reason, I find myself wanting to know more about this...thing, the creature. As descriptive as you get with what it looks like I feel like there needs to be more story behind it.
Keep it up!
