I favourite things on the spur of the moment, however i always go back through my favourite's to see if they still appeal to me, if not i remove them, though i always go through the artists gallery to check if there is anything else i like. :)
Also i suggest everyone check out the devi's of peoples on my friends list thingy, as if you like my art you will love theirs as it is a thousands times better
JUST TO MAKE CLEAR - Though i doubt that anyone would use my artwork, please don't without getting my permission first
