Oh what to do!

Hello friends of deviant art! I know it have been a while that I haven't show any new art lately but I'm trying to clean out my gallery before adding new drawings. I'm kinda stuck though because I have some old stuff that are really popular to other people.
should I just stuff them all together in a folder or delete some I don't like even though other people like to add it in their favorites?    

what do you think is the best idea?
