If I find someone really good, I face two of there deviations that I really like. As in, my FAVORITES of their work. Because that's what favorites are xD I can still favorite random things that I like though as well. Then there are the people that can make drawings and epic pictures that are superrealistic or huge. And they do this everyday. When it comes to those people, I favorite all of their stuff xD
I am sort of. I fave things according to an artists' own skill, so I fave the best of peoples' work. The best of Alice might not match the worst of Bob, but I know Bob can do better and don't fave it, and Alice can't (yet!) and do.
Stamp faved are whichever ones I agree with that ALSO look good (it must be BOTH!).
