Blotches in Yellow

This reminds my mom of cheetah spots.

These are separate views in different lightings, but yellow doesn't do well in certain lightings, does it? Looks like what worked for my red and blue ones won't work for this color, even though I added yellow ochre for obviousness, but all else I added were lemon yellow and brilliant yellow.

View 2 was taken because there was an unwanted shadow in view 1, but because it was too dark, I tried taking view 3.
