I have a strong feeling this could very well be FF XIV fanart. Especially with the scales of the one on the right. That looks very Au Ra to me. Here's the deviant art page that shows a full picture for a sample page: https://www.deviantart.com/hoshiineko/art/2020-commission-samples-841894437 But there isn't anything indicating it is FF XIV art. So I won't tag it as such.
