Instead of comparing No. 1 with all six other people, compare No. 1 with No. 2.
Then No. 2 with No. 3.
Continue across the line.
This can make subtle differences easier to see.
3. Examine the face
Look at:
jawline
chin
cheeks
eyebrows
eyes
nose
mouth
forehead
Don’t rely on a single characteristic. Look at the overall pattern.
4. Look at the neck and shoulders
Sometimes the difference in a puzzle isn’t in the face at all.
The neck and shoulder area can reveal differences in the way a
person is proportioned or posed.
5. Check the clothing
Even when everyone appears to wear the same uniform, there may be small differences.
Look at the:
tie
collar
shirt
buttons
skirt
socks
shoes
positioning of the clothing
6. Look at posture
One person might stand differently.
Perhaps their shoulders are positioned differently, their feet point in another direction, or their hands are held differently.
These tiny details can be surprisingly useful.
