Wow. Thanks for the link. Your are right Karin, I have to slow down (and let my subject slow down as well)
In most of these portraits there is a suggestion of 'free & playful' just by being outdoors (as well as just by being children) I don't have a photo of what I had in mind, just an idea in my head. I'm sure I am making this harder than it needs to be. Thanks again for your input and suggestions, I will try again & post my results before choosing.
BTW I am happy for this new section. It will certainly help those of us who struggle with 'what to paint' as much or more than 'how to paint'.
