Challenge Hesitation

Hey, guys. I came up with some ideas for Challenges, but I'm hesitant to post them because (a) I haven't selected winners for my last one and (b) I don't know if I have time or inspiration to give prizes. Should I just do it anyway?

Also, would it be selfish to have a "draw my OCs" type of thing? I ask because one of my ongoing stories is turning five (!) and one just turned 10 (!!), and I want to celebrate somehow. "Then why don't you write more?" asks just about everyone.
