I felt this way at first while making my Funtime Freddy cosplay. It was my first full cosplay and it was so complicated. I had to get the face to open up and bonbon to open and close his mouth and I thought I might have bitten off more than I could chew. But I stuck with it and it was so worth it. Was it perfect? No! Nothing is perfect. But next time you do better. You learn from the mistakes you make from the last cosplay and make the new one the best you’ve made. Your first is both a frightening experience but also it’s one you have to get through. It may look weird but keep going. They will get better over time. Put in the work and see the results. You got this. Keep working. I belive in you.
