Very cute!
I enjoyed your one-shot of Korra and the mysterious thief a lot! I have to admit my heart skipped a bit when you introduced the thief as Wan. Even though he was a minor character in the show, Wan was totally my favorite. And the animation for that section! Wistful sigh.
Anyways, there are a few things I think could help you improve your writing even further. One thing I try to be aware of when I write is my sentence structure. I find that a good way to keep the story flowing is to change the structure of the sentence. For example, your first three paragraphs all start the sentences off with "she" or Korra. Instead, you might try to start with a verb, like "Grabbing the bag of papayas, Korra continued her walk". It keeps the readers interest when you surprise them with a unique sentence like that.
Also, your punctuation and spelling are off in a few places. I too struggle immensely with this. I am absolutely dead horrible at spelling, but thankfully I discovered the most magical of websites. If I could marry a website, this one would be it (well there are a lot of websites I would want to marry, but polygamy is a no no so...). The site is called grammarly.com. It's seriously fantastic. It'll tell you where to put commas, apostrophes, when you've spelled a word wrong, or if you have the wrong version of there or their, etc. I highly recommend it.
But well done! This could be a wonderful story with a little more TLC. Keep up the good work!
