What a good idea! You should create a thread on /req/ !
That's called /art/.
Did you check /lit/? There's a thread pretty similar to this, here: https://www.gurochan.cx/lit/res/6590.html
I can start a Drawthread,but i don´t know if i should put it on /req/ or /art/.
Try /art/? Since drawthreads are not exclusively about requests.
Drawthread is up and running!
