OK guys, following the feedback I re-edited the shot. This is it now with zero skin smoothing and also dialled the orange down a bit. Better?

Callum's looking even more perfect than before!
That skin looks exactly right, now.
Well done, you!!!
And as you said, you mostly shot landscapes before your lad was born. Shooting "portraits" is quite a lot different.
Just get ready for when he can outrun the AF on your 5D2 and you'll be in here asking about "How to photograph my son's sports day"...
