Yes!  Looks great.  

I was about to post when I saw this earlier today saying you should animate it. I come back in the afternoon and it's animated. : )

I think it'd be a nice touch if the face stretched a little horizontally when the slime bobs down. Good job though.

 Does it look any better like this?

No offense, but I think you should have animated something as simple as this.  It's still a pretty good avatar, though.
