Freakin creepy and Awesome!! maybe try and clean up the hair strands taht are on the inside mouths... a little bit of clone brush will do ya! fantastic job! GL!

Looks great! Wow..

Many people has done that (for example http://chain.deviantart.com/art/Eternal-scream-66319159) and your work has a technical problem: the biggest and the second mouth look different from the rest, maybe you distorted them too much

I agree with Langstrum on the fact that some mouths appear a tad too distorted (it's a tricky problem to fix, I'm sure), but I really like how you made the mouths twirl into a spiral, rather than just placing one inside another. It's a effectively dizzying representation of the droste. Good luck! Witholding my vote in case you fix the distortion problem.

You get your idea from this? http://www.pxleyes.com/blog/wp-content/uploads/50-shockingly-disturbing-photo-manipulations/26.jpg
