When I watched the movie, upon seeing the arrival of Tempest, the first thing that surprised me is how far her leg went. I was inspired to draw this pose when I saw and actual pose of a horse doing this, and I immediately pictured either Tempest or Applejack. I might end up making another bucking picture of Applejack and put them together. I planned on making one with no clothes, then one with her uniform, then another in a cute sports outfit. I may end up posting that version some time later, as I haven't done it yet. I really couldn't decide which version to post so....there are a lot. I really wanted to bring out her muscles, so I went with a different form of shading for this one.

I've been hoping that Tempest will end up making an appearance in the show, and if she does, that would be great. I thought that after her reformation, after the battle with the Storm King, she would then need to get comfortable with her new surroundings, and figure out what she is gonna do with herself, now that she no longer works for Storm. I first thought she would stay in Twilight's castle to settle, but then I thought that after it being suggested by Twilight, that Tempest would go to Sweet Apple Acres to relax, spend some time with the few members of the Apple family living there, and just prepare herself to make more friends. Since everyone saw how good her bucking seemed to be, she became a great help in harvesting the apples. Another reason for her to go, to do something she always had done to practice fighting, something she highly enjoyed, and she would be making some pay of her own till she settles, finds her own home, and is comfortable being in Equestria again.
The reason it was suggested in the first place was because Tempest was feeling a bit overwhelmed with being around all the ponies in Ponyville, especially since there are always some who still judge. She just felt out of place after being gone so long. So with Applejack giving her a list of rough, tiring chores, Tempest is learning to relax in her new life, and has never felt happier. She sends letters to Twilight when neither can visit.
At some point, I pictured Applejack playing Buckball with Applebloom, when she convinces Tempest to try it out (hence the picture), and she is again wowed at Tempest's leg span. That's when she welcomes Applejack to come practice for next seasons Buckball, and Tempest thinks about accepting it.
After about a year or two, Tempest is offered to be the first official guard of Twilight's castle, to be a captain. Since Twilight's castle is so empty, and she is the only one with no form of security around the place, Celestia informed her that now would be a good idea.
