Your very selective use of the white is amazing. Really pulls everything together and adds to the playful-creepiness of the piece.
Also the positions/stances/expressions of some of the zombies are so hilariously adorable I just want to hug them.
lighting, scene, and creep-o zombies. Foreground - Background...very cool, the eerie glow of the eyes on 'em is so sweet. Well managed.
greyscale pixel art is difficult to appreciate if there's lighter colors around ( even the grey of PJ ); to really appreciate this kind of image I need to download it and watch it on a black background
This is... flippin' amazing. Seriously some of the best greyscale pixel art I've seen for a long time.
I demand moar!
Nice, you change it already! This scene still looks absolutely fantastic like this. Very nice job!
Maybe you can change the sky provisionally (only for PJ gallery), because it would be really sad not to see this accepted on the gallery.
yes you're right . the sky was taken from a foto . doest it mean approval is not validated?
Yeah, I'm agree, the sky is NPA. This is pity because the whole scene it's a really nice piece.
This looks awesome!
The second last pixel you posted was a really long time ago 
Well done
