Ooh stuff!
So, I read it. This will be good criticism practice.

Your opening three sentences sound wonderful, I really like them.
After that, your pacing is a little odd because you essentially stop the story to describe the fox.
Then you rush at break-neck speed towards plot! Too fast ahhhh!

My advice is...

If you're starting with a nice, easy opening, take advantage of it. It is a beautiful opening, and you can definitely exploit that.
Use flowing description. Have your fox do something while you describe him so it doesn't feel like your story has stopped in its tracks.
Careful of tense - you broke it once, maybe twice.

Finally, this is just general advice: if you want a really good edit, read your story aloud to yourself and mark down or change the sentences that you feel need it. Failing that, have someone else read it aloud and have them simply circle the awkward parts.

Happy writing ^_^ I hope this is useful!

Also, thanks for the universally compatible format. I post all of my stuff in docx due to laziness. PDF is also a nice one to use.

Thank you, this will be helpful for future writings and ill get to editing it soon!
