Hey Amin Ko...it doesn't look like anyone else has brought this up, but it looks like part of your bust did not get painted.
You can see the area in the first pic compared to the same area on the opposite side of the head.
There's some paint missing there.
Just check mine today and it looks fine with equal paint. Maybe my scans are merely reflection of the light.
Thks
