Snape would likely have a very critical view. Given his sharp intellect and his own deep understanding of the wizarding world and the characters in it. If he reads the epilogue fanfiction, he might scoff at any inaccuracies or misinterpretations of the characters' personalities. He could also be a bit sad, thinking about how things could have been different for him in the future depicted in the fanfiction.
He might be quite surprised. The fanfiction could present alternative versions of the characters' futures that are very different from what he experienced. It could make him reflect on his own life and the events that led to the epilogue in the original story.
One thing to note is that the fanfiction might deviate from the original canon. So, while Hogwarts is a magical place, in the fanfiction, the events in the epilogue could be reimagined in unexpected ways. For example, relationships between characters might be explored differently.
Given Snape's reserved and often brooding personality, he would likely read the epilogue fanfiction in solitude and really take his time to analyze it. His pride in his own knowledge of the wizarding world would make him either dismissive of any new ideas in the fanfiction that he doesn't agree with, or grudgingly impressed if there are some well - thought - out concepts. His past experiences, especially his complex relationship with Harry and the other students, would also play a role in how he reacts to the fanfiction.

One great Snape as Head of Slytherin fanfiction is 'The Slytherin Legacy'. It delves into how Snape shapes the Slytherin house in ways different from the original series. His strict yet fair leadership is really well - portrayed, and the interactions between him and the students are both interesting and full of the Slytherin - like intrigue.
There's also 'Snape's Hidden Past with James Potter'. This fanfiction explores Snape's side of the story more. It reveals some secrets about his early interactions with James that were not shown in the original books. It gives a more sympathetic view of Snape and shows how James, in some ways, misjudged him all those years ago.
I really like 'Shifting Alliances' in this genre. The story delves deep into the complex relationships between Hermione, Snape, and Draco. Snape's hidden motives and Draco's struggle between his family's expectations and his own evolving beliefs, all while Hermione tries to navigate through this web of secrets, make for a fascinating read.

One great 'Harry Potter Snape and Lily' fanfiction is 'The Lily and Snape Chronicles'. It delves deep into their relationship from their Hogwarts days.

The story is filled with beautiful descriptions of their interactions and the emotions that came with it.
