Hi Valerie,
Your rendering is good but I find that your colour palette has to much grey in the dark and half tones ( in the hair, face and blue dress). Don't forget to use the '' colours of rainbow'' rule ! Sans cela on perd l'éclat dans les couleurs, elles ne peuvent pas garder leur intensités.
- Observe in close up the colour modification of the hair & skin tone.
- Use warmer dark for the hand ( see close up)
- More intense , nicer blue ( si je me rappelle bien du modele)for dark tone of the dress.
