Wow no I didn't notice, I only noticed when you said it was a creature. Now the the whole thing looks better :P.

Um without knowing it's a creature it just looks like it's brigher at the end. I almost didn't notice that the light line in it was it's eye.

I don't know what do suggest to make this more noticable. Maybe a mouth? or stronger eye. Maybe make everything a bit darker to draw the it as a focal point. Not really sure though.

But now I really like it :P Maybe a bit to long only the bottom half is really require but the other is done well.
