Good thinking. In keeping with your title the faces might look happier but I still like your idea.

Nice commentary on today's way of society, and nice change on the angles. Well done!

wow that is smthn

I like your concept! GL

Love the texture and the M.C. Escher-ness of it. Well done!

This could make a really exotic wall decoration

Dunno why, but it makes me think of something you'd see on Pee Wee's Playhouse. LOL Nicely done!

There wouldn't be a drop shadow against the sky.

for me seems that it's without depth of field.. CMYK46 writed nice, a drop shadow against the sky makes all difference... GL

Agree with CMYK46 on the drop shadow. The sky is a light source, and a shadow would not show against it. Otherwise, the concept and stone texture is excellent!

Looks good. You do need to add the source link for the lightening even if it's a brush.

The correct link for the brushes is :

Very Oz-like. Nice!
