Only reason why I haven't created an account yet is because I haven't found a way to clearly upload any of my sketches/drawings/traditional stuff. And I don't think they let you upload true animations outside of Gifs, so I can't upload any of those either. I might create one. If you're writing some Destiny fiction (which is actually a really cool idea that I haven't even thought about doing), then your best bet would be fanfiction.net. The universe itself is still new and young, so there's a good chance that you're going to get a decent amount of feedback. The reason why that's important is because in universes that have been around for a while (pretty much anything with more than 2-3k stories), the only people who get good feedback are the popular ones, no matter how good you write. (I can testify to this personally. I don't like to brag, but I do think I put in far more time and effort than 98% of those cheesy ass love stories in Halo) You should link it and I can give you some feedback on here.
