At the beginning of designing the character, in order to facilitate animation production, the character's feet were designed in their current shape, with a black line. It has no direction. It's actually a straight line and an oblique line. This meets my animation needs. In my animation, I only used the first two images for the legs. What you're saying is repetitive, it's because I'm afraid there will be new demands in the future and reserved space. The image of the shield was also designed by me according to my animation requirements, and the existing 8 angles meet my animation needs. The feet and shield are not designed like other body components. So four directions are not necessary. The repeated shield is also a reserved position for me.
