While there is precious little in the way of explanation for the background of the story, that's probably fine since Groundhog Day is one of those classics that are referenced to this day in pop culture so damn near everyone knows at least the premise. However, there are some references, such as Phil regretting not getting Ned's phone number, that mean nothing to someone like myself who has not watched the Groundhog Day musical (or has not seen the film, assuming Ned is in that and matters to the same degree, because I have no idea). Not huge problems really, since the plot was about Phil's life after getting out of the single day loop rather than what happened in it, so no big deal there.
There was, however, one major negative point in this story. The dialogue felt extremely stilted and unnatural, like they were robots constructing sentences rather than people speaking normally. It's hard to explain without example, so I'll do the example thing. This sentence is a solid example of what I'm talking about: “So, now that we have seen the sun rise, where do you want to go Rita? We got the day off still, do you want to go to the weather museum?” To make it not so robotic I would tweak it to give it more of a normal speaking flow by cutting out some of the extraneous words and rearranging a bit: "So, now that we've seen the sunrise, where do you want to go? We still have the day off, want to go to the weather museum?" Minor tweaks, as you can see, but it makes a world of difference in how smoothly it reads.
That aside, this was a decent entry. The writing outside of the dialogue was alright, the plot made sense (though the time jumps made it feel rushed), and Phil and Rita got reasonable levels of character development given the length of the piece. It's a neat premise too, showing life after the crazy events of the canon shenanigans. Overall I'd say it's alright, not spectacular but not awful either.
