Exactly they have changed over the years. How they look now is far from the original origin. As you say it's capturing the character, and that's what I try to improve on more than exact measurementsThe body is basically composed of about 7-8 ‘wedges’. The shape of them though is sort of like if you flattened and egg into two dimensions. I’ll find one of my older patterns and post it again to give you an idea. After all my builds, I still find the body to be the biggest pain to make; the smallest variations in the shape of the wedges can result in a big change in the overal shape of his body.
Great job!! And you are correct; a lot of it is trial and error, and also very close observation of the references. Thanks for sharing your process. It’s important to know there are many ways to go about making these! The right way is..whatever works! I’m pretty sure the original Muppets ran on this thought as well. I often tell people to not be overly stressed about it; the Muppets themselves have changed so drastically over the years. There is no ‘one’ Kermit, or any other Muppet. Try to capture the essence of the character, and it’ll work. Your Fozzie looks amazing!! He’s one of my personal favorite characters.
My Fozzie is looking a little grumpy but I know and I can see the changes that's needed because of the first attempt. Hopefully I can finish him when I get money, As I'm eager to make another to make the changes. But I'm glad you like him so far he's part of my trio of favourite muppets.
