One of a few survivors of a race from another planet lands in Equestria from space. He becomes seriously injured and close to death.

However thanks to the kindness of a group of mares, his life is given another chance and will be given opportunities express his gratitude in ways he wouldn't expect.

The picture is mine from deviantart. However the description for it is different from what is in the story.

This story was inspired by I-C-U-P and DryvernX. And I'd also recommend reading their stories.
