Yes, Dragyn. You SHOULD.
Good job with the story. Well-developed setting, obvious conflict, pointed resolution. Your stories are always very solid. However, it might be interesting to spice up the relationship with the apprentice and his master a bit more. Do they REALLY like each other? (Interpret that both ways) What in their lives has come between them to bond them, separate them? How does this next transformation determine the shape not only of their physical forms, but of their mental forms as well? Is he going to be able to write back with a fox's paws very well?
What I mean is, your story is very solid, but a few good details might give it the punch it needs to become a sick-nasty story, rather than just a great one.
It's a good thing you're writing again!
(I ought to get around to reading all the stories you've written...)
