I think this challenge is awesome. It's amazing to see how creative people are and what people can come up with when they stare at a pretty ordinaty bubble. There really are no limits for imagination.

The shading is what I like the most about this piece.

Very convincing: it has dynamic qualities and it's hard to guess that the shape was fixed beforehand. I would like to see the face better, though... Anyway, best of the challenge IMO!

Admirable imagination. This one's gonna rank first in this challenge I suspect. Very nicely done job.

Haha amazing! :-D So well done. 

 woah i like it! :D

Great imagination =)

 Current version solves it well enough I think.

I'll try that. When making it I couldn't think of a 'good' way to make it not look like two left feet.

 I'd be inclined to try ball out, toes up and back to solve the two-left-feet problem.

Good!!! I'll vote your piece for sure.

 Creative and dynamic! 

 Proper good

You've got my vote so far! Awesome stuff!!!

Is very original, great work!!

This has to be one of the best entries yet. <3

Impressive entry on its own but certainly stands out from the others so far.

Awesome

cool concept

Fits the silhouette perfectly. Great Idea and very solid execution.

Gotta vote that one up!

Yeah, that's really creative! I like it a lot. Colors are nice too, I like the way the purples/greens interact.

 Hahahahahaha, excellent idea.

Woah. That's something I would never think of looking at silhouette. Impressive pixels here.
