Everyone has to start somewhere anon, and you have to make mistakes to learn. If you start, just know that your first few costumes will probably be a little rough, but they will teach you so much. If you choose to post them online, dont act like youre the best thing since sliced bread, admit that you know things are wrong but youre happy with the outcome and how much you learned along the way.
And if you want to git gud, work hard. Look up tutorials, ask questions, look at other people's costumes and think about what you like about their costume and how it was constructed. Like anything, you have to cosplay a lot and have a lot of patience to become great.
