Hi megazx^^
Please remember to check your scans quality before you upload. Your Persona 5 scans all had a bunch of jpeg artifacts.
And to clarify what JPEG artifacts mean, another visual example:
If you look around the outlines, especially on the dark purple hair, you will notice some fuzziness. That's not supposed to be there.
Saving images at a high quality is a must, since some colors (red, especially) are sensitive to drops in quality. Saving a mostly red image at 7 quality instead of 10, 11, or 12 will give you an image full of artifacts, like below:
