Thank you guys for your comments !!
You're right Alpal, some contrast can be added... I think we can play with the curves for a long time, and the result will always be better for someone.
Thnak for having taken time for the example !!

Is it better ? I really don't know. The 3 of us always prefer something more... pastel than something to strong. This version of the picture was perfect for us.
We noticed that you guys in Autralia (and also in the US) always go further with the curves than we do... But it concernes just the last 2% of the treatment, max
Once again, thanks for comments !
