Not sure if we have it already and I'm just missing it. But are there any kind of render or drawing challenges on this site. Not like the contest where there judging or voting just a unifying theme for subject matter in artwork. Like pick an idea like say "flying". As long as someone or something is flying either by their own power or mechanical device somewhere in the image.

The Renderosity Magazine weekly art challenge  ?

They're sometimes posted in the Contest Announcements forum, e.g Week 8 - Road, but check Renderosity Magazine to be sure not to miss them. Apparently the theme changes weekly on Wednesday.

Thanks for responding I sometimes forget the look over the magazine.
