Do I need to finish this short story or is it good enough as-is?

[OpalCat]

This is a story I wrote when I was 19 years old. At the time I didn't consider it to be finished, but I've always liked it and thought "I'll finish it one day"... but when I look at it, I can't think of anything else to write about it. What do you think? Where should it go from here?
