“Unsplash grants you an irrevocable, nonexclusive, worldwide copyright license to download, copy, modify, distribute, perform, and use photos from Unsplash for free, including for commercial purposes, without permission from or attributing the photographer or Unsplash. This license does not include the right to compile photos from Unsplash to replicate a similar or competing service.”
However, it also states:
"This means that Photos on the Service come with a very, very broad copyright license under the Unsplash License. This is why we say that they are “Free to Use.” Note that the Unsplash License does not include the right to use:
Trademarks, logos, or brands that appear in Photos
People’s images if they are recognizable in the Photos
Works of art or authorship that appear in Photos
If you download photos with any of these depicted in them, you may need the permission of the brand owner of the brand or work of authorship or individual depending on how you use the Photo. Please see our FAQs for more information and, if you still aren’t sure, you should probably talk to a lawyer who knows about these things."
So, since the image you shared clearly has a person’s image that is recognizable you may want to reach out to the photographer first.
