actually I think the flatness of the body is pretty faithful to the concept art, http://lysol-jones.deviantart.com/art/Downgrade-Virals-140298485, it looks fine to me.
I've been following your stuff on deviant art, looks great!
Also, showing some more of the top of the little yellow cylinders :)
Really fluid animation, I like :D
Giving the body segments a bright highlight will create the rounded look the others are talking about. Also pay attention to the nubs sticking out of the segments, the ones on the bottom should be a darker shade of orange compared to the ones on top since they are in shadow. Great motion on this.
Nice, but I agree with Ninja Crow. Perhaps it needs a slight angle to it, like the head, to give it some depth :)
I cant see how you have the patience to make this, its so awesome xD
This is cool, but looks a bit too much like a flat paper streamer, rather than a tubular worm enemy.
Love the head on it, though!
(plz keep 'em coming!)
Trippy!
