Some Avengers would be happy. Like Thor, he would laugh heartily at the fanart that makes him look like a big, friendly giant. In fanfiction, if he's depicted as a noble and powerful being, he'd be all for it. Black Widow might be more skeptical. She'd analyze the fanart and fanfiction carefully to make sure it doesn't give away any secrets or misportray her. She might be okay with the fanart that shows her in a sleek, stealthy way.
