Thanks Alexandra
As the customer signed off at the last sitting im a bit hesitant to touch it further although i would love to get stuck in and find a solution. Im keen to learn from this so as soon as i got home i tried some samples using your advise above.
(My daughter also helped by dragging a plastic pony over the wet canvas and onto the carpet while i was cleaning up
Ive worded my trial below:
Cerulean Blue / Naples Yellow Hue touch of umber and white in the light area and Indian Yellow / Permanent Sap green mix dab of Burnt Umber in the shadow with a touch of Jaune Brillant showing through in the transition and shadow area.
I also did a cad yellow / ultramarine blue test but really struggled controlling the area in the darkest shadow where i need to create unity with the red gown resulting in a muddy purple/brown in the shadow area. I will continue to experiment using your advise and hopefully in my next painting you will see an improvement.
Thanks Jayden Dickinson.
