The cherry cape is not mirrored on the underside of the texture, leading to an apparent misalignment with the sides of the texture.

Steps to reproduce:

^{(Creative Mode)}

1. Enter the third-person view
2. Continually fly forwards
3. Rotate the camera so that the view is under the cape, to either the east or west side

Texture:

^{(Both screenshots face the back side of the cape, in BlockBench)}
Current:

Fix:

Notes:

There are also a few pixels on the cherry cape texture which look unusual, and cause different faces of the texture to not align properly.
Two on the top, one on the east face, two on the back, one on the front, and one on the bottom:

To fix all the misalignment issues to create a completely seamless texture would require this fix:

Because the independent misaligned pixels are more nitpicky, and may not warrant another report, I had opted to leave this in a note because it would be beneficial to fix the misalignments in tandom with the (currently) flipped back side.
