Incredibly fascinating animation.
The viscosity reminds me more of molten marshmallows than smoke. Nevertheless, sublime entry.
Damn, I expected that... I would've added a background if it wasn't for the challenge, and having just two pixels of transparency for the eyes felt a bit like cheating. I probably could've made the ground transparent, or something.
Well, I'll figure something out and edit it in a week (I don't think I can do that while the challenge is... active).
I agree with @adam
I too have the light pixeljoint background and it ruined the picture as a whole.
I would suggest uploading her with a background. My light pixeljoint theme destroys the outer AA.
Great fluid movement by the way.
And you're absolutely right about the viscosity.
