I hate when people delete their own art, most of the time the reason is "well I gotten better" Well News Flash: that the same with even child prodigies. and putting a deviation in storage means nothing if you never take it out of storage.
My view is, if at least one person Favs your work, even if you don't like it that much, it would be unfair to that person if you take it down. (It is that logic that prevents me form delete things in the scarp folder). However if DA upload your drawing more then once and you take down one or they forces you to take it down (most of the time they over reacting) that different.
Point is, I rather have your art up here forever (or until you delete your account) then to hunt it down on some Thread were it will last for only a short time (what ever happened to "it stays on the internet)
