This was a very interesting video, thanks for posting! I sell fanart in conventions, but since it's a limited amount of prints (unlike DA, which will keep printing for you, I guess!) it's less under the radar probably. XD Even though it's still quite dubious, yes.
Yeah I always wondered that. Like pairing two unoriginal characters together and then selling mass prints to people for profits. I always really just thought it was kind of...rude. I don't feel the same about personal people wanting to see a loved character in your style and personally pay you to do that. But the way it runs in Comic con, I always found it strange.
