I work professionally with art and deal with portfolios a lot, and my best advise from my experience is that fanart is OKAY, but many places would really love to see your original work - they won't discriminate from fanart, especially if it's in your own style (i.e. Your Sombra or Mercy will work, because it's not in the style of the original creators). I would still encourage you to create some original work, since many places want to see your ideas and aesthetic.
OKAY!! Thank you!! I was hoping to put mercy and sombra in there hehe I will try to make more original pieces
