in the first post of every page, challenge the people below to draw something (in any medium, it can be pixel art, rendered 3D model, pencil+paper, toast, basically anything other than photography, people below choose. Tracing a photo counts as drawing for our purposes as well. You might just be called lazy.)
If you're not the first poster on the page and a challenge has been posted, just post "Reserved" if you want to participate in that challenge, then draw the thing!
Feel free to judge other art that's already been posted, but don't be mean. Don't say "it sucks" say "X is a problem" or "You need to practice X more". Constructive criticism.
This page's challenge is to draw someone with a TV as a head.
