MY ARTWORK IS DIRTY

I turned in my artwork last week. Wait... no... it was this week. I don't know what's going on anymore. I turned it in on monday. My issue is that I'm not very good about keeping it clean--dust free, dirt free, paint fleck free, etc. So I guess when they scanned in some of it there were some issues with specks and such showing up. IF I bothered to cover my artwork with sheets of paper and nicely put it away instead of throwing it all over the floor then this wouldn't be a problem. I never learn my lesson. Maybe I will next time around?
