I have 5 old unfinished pictures in my studio that I cant delete. I just dont have the option. On the bottom of the page, where it normally says, update or delete, there is only update. I thought making them finished would give me back delete that, but it didnt. So, what should I do? Please help.

you have to submit them real quick, then delete them... I will be watching for them lol... j/k

After a certain time the picture sets and only the mods can delete them. I see it this way, you have extra canvases, especially helpfull if you find yourself at your limit of pictures and want to draw something.
