in your template the proportions look different sizes then in the video. the big long piece on top of the head in the video is narrower then the one in the 1st template page. ive got some idea of how to make it work.
bruh that's funny, i was looking at the first page of the templates and thought that part of the image was cutout so i cheeked by laying the 2nd paper i sketched out on the screen and looked over and noticed that i sketched out the other side of the pieces without knowing what those where for.
