Different and good
I do like this, I mean, it is good vector art but then it started to animate and I was like "WHOA" and then it moved more in this lava lamp like flow that kept me interested. I love the light greens with a bit of transparent flow to them and the background is good and works with the rest of the piece and the animation itself. I do love the face on this guy, very different and unique.
~~THINGS TO IMPROVE ON~~
I don't think you need to change anything but you should make an animation out of this, a full one
