Hey, this is a nice thread. I've always loved the concept behind spirits. They're like when you played with toys as a kid and you wished you owned a toy of a certain character, so you instead imagine a toy you already own as that character. Essentially you're putting the 'spirit' of that character into the toy.
Here's a bunch of spirits I've done based on various franchises. I'm still learning all the ropes to this site so I'll hold out on trying to find images of all these characters for now.
