I'm not sure what you did, but 3 out of the 4 pictures look unbelievably poor with respect to the uniformity of the light distribution. But this certainly has nothing do do with a small scratch.
Your earlier picture of the stuffed toys on the bed also has strange streaks. I'm not sure if this is caused by flare, by reflective surfaces on the side, or by big dirt streaks on the lens and/or sensor.
