Next challenge voting BIG prizes involved

I want to make another challenge. I really need everyone's help for picking what should be my next challenge.

Fan Art: Draw my OC's -3
-I would like you to draw one of more of my OC's for this challenge. This also includes my adopts. That means I'm trusting everyone on here that you WILL NOT steal any of my files for my adopts and use them as their own. If this happens I will hunt you down and gut you like a deer.

Wallpaper: Opening and Ending's -2
-I would like you to take one or more of your favorite anime opening's and endings and create a wallpaper based off said song. It doesn't have to be with the anime that you found it with.

Fan Art: OC's Galore!!
-I want you to draw your OC's, a friends OC's, my OC's, whatever you would like to do! It just has to be with OC's. Yes Adopts are allowed for this as well. You play with them and develop their character so they are yours after all. YOu can draw them with their lover(s), friends, by themselves it doesn't matter. The main goal is to give OC's lots of lovin!
