Hi HirotoKai! Nice work and thanks for fixing the image size of the boots. Here’s some feedback:
Kimono: There’s some clipping on the avatar’s right side, between the hand and the kimono. Also, the ring of neck vertices has been altered so it doesn’t fit quite right with the avatar head and neck. You may want to add the ring of vertices around the hips and connect that to the kimono so that it connects to a greater variety of lower half wearables.
One last thing, the thumbnail images here might be better off in a slightly different size. Decentraland reads images better when their size in pixels is a power of two, like 256 x 256 px and 512 x 512 px. These thumbnails are 215 x 215 px, if you wanted to increase them to 256 x 256 px it may avoid issues in world.
