My sister looked at the drawing and said his face was too narrow so I widened the jaw line and neck plus narrowed the forehead just a bit. A few areas were darkened and lowered the nose just a small fraction. She was right, this does look more like my nephew. There is a slightly darker line beneath his left eye, next to the light area, that needs to be lightened to blend in more with the skin tones - other than that I'm calling this one done.
On a different note, we have daffodil sprouts showing even though it was a cold 16F this morning. Spring is on the way and I'm thrilled.
